Chapter One

It was a beautiful spring morning down in Ponyville and the season was in full swing. The sun shined on a colorful scene as birds fluttered around and flowers of all colors bloomed in the warmth. The air was cool, nothing that would merit a light jacket or a scarf, but summer was certainly well away despite how warm outside had gotten. It was the kind of weather that wasn’t quite cold drink weather, but a quick swim in the lake wasn’t totally out of the question.

Fluttershy was spending the afternoon in the garden behind Sugarcube Corner. The colors of spring surrounded her seat as the cutest little animals scurried about the bushes and trees. Mrs. Cake had set up a cute little table on the patio there, big enough to provide enough room for both of them. And on the metal table sat a yellow ceramic platter with a pot of hot tea and a pair of tea cups balanced on top. A checkered towel laid spread out across the table’s surface, serving as the perfect place for a smaller plate of cookies and tiny cakes to sit.

Across the table, past the tea and cakes, sat the motherly mare Mrs. Cake herself peacefully sipping on a warm cup of tea that balances itself on a blue and white floral saucer. She always had this warm glow about her. A trusting and sincere presence that Fluttershy seemed to be naturally drawn to. She felt more comfortable talking about a number of things with her that she never even dreamed of sharing with her friends.

During their friendly tea times the two mares would talk about a number of things. Curious dreams they had recently, aspirations for the future, weekend plans, and even opinions on fashion trends. Every topic just flowed seamlessly from one another as both ponies were more than happy to contribute to the chatter.

As many things do, conversation started to steer towards more intimate topics. The kind of topics that were only talked about between trusting individuals and in a hushed tone while they made sure no one was around to eavesdrop. It was the kind of topics that made Fluttershy blush and grow even quieter than usual about.

One such topic, which was strange to even come up at all in normal conversation, were ponies who enjoy wearing diapers for fun. Even looking back at it herself, Fluttershy couldn’t quite pinpoint when such a thing was mentioned, but something in her, whether it be curiosity or genuine interest, brought her into the fold. The subject developed itself over a month’s worth of tea chatter. One of them mentioned it in passing and the other returned with some questions and opinions. This eventually lead to Fluttershy’s clear interest in wearing a diaper herself which Mrs. Cake was more than willing to encourage and nurture as she did so well.

“Do you ever plan on wearing one?” Mrs. Cake finally asked on this particular tea date, ”you talk about it so fondly.”

“No no, I couldn’t” Fluttershy said with a blush, ”talking about it is just fine.”

“Oh sweetie, all we do is talk about it,” Mrs. Cake sighed, “don’t you want to go out and try things first hand? Just to see what it’s like?”

“Well...I don’t know,” Fluttershy fidgeted, “wh-what if I end up not liking it or somepony else finds me wearing one a-and what if they think I’m some kind of freak?”

“Tell you what,” Mrs. Cake said, pausing for a moment as she gently placed her tea cup back onto its saucer, ”I’m having a little get together for ponies curious about it as well this Saturday. Why don’t you come on by?”

Saturday? That was practically right now! She couldn’t! She wouldn’t! It wasn’t that she didn’t want to go, it was just so soon! Her worried mind conjured up false reasons on why Saturday would be impossible. She might have needed to keep her weekends open in case a friend of hers wants her to come over for a visit. No, Saturday was certainly too short notice.

“S-so soon?” Fluttershy squeaked, “b-but I don’t think I’d be ready.”

“I understand the nerves, but I feel like it would really help you explore this special side of yourself,” “would you please come? If not for yourself than for me?”

A pang of guilt stabbed Fluttershy in the gut. Mrs. Cake’s request suddenly felt all the more alluring. Above all else, she didn’t want to let the motherly mare down. That would just be so devastating.

“Well...alright...I’ll go,” Fluttershy finally sighed.

The answer made Mrs. Cake smile. “You’ll enjoy yourself,” she winked, “I promise.”

Author's Note

I realize now that I have quite a couple unfinished stories floating about. Rest assured that I'll be coming back to various stories from time to time as the inspiration strikes me. My muse is a fickle brat that isn't always so consistent. For now please enjoy the start of this little diaper story staring Fluttershy. Future plans will include sexual diaper play which the nervous pony will slowly step into as time goes on!

Chapter Two

The couple days that followed were, to say the least, incredibly nerve wracking for Fluttershy. Her mind was plagued with worries and anxieties of the coming Saturday. When the day finally did come, she was tense with worry and she had already thought up a dozen what-if scenarios that would end up in complete disaster.

She traveled across town to Sugarcube Corner. On any other day, the place would be a social centerpoint, drawing ponies of all ages to buy and sample the delicious selections of cakes and cookies Mr. and Mrs. Cake had to offer. However today the building looked particularly barren and a sign that said “Closed” hung on the door.

Taking a deep breath, she knocked on the door and stood there to await her fate. Perhaps she had the date wrong? What if the party was someplace else? Maybe she should go home and forget about the whole thing.

Just as she was about to turn around and give up, the front door began to open. Standing before her stood Mrs. Cake, as motherly and supportive as she looked during their little tea date just a few days ago.

“Oh wonderful, you made it!” Mrs. Cake smiled, “come in! Come in!” The motherly mare briskly ushered Fluttershy in, shutting the door behind them. “You’re just in time. The party’s just getting started!”

Once inside, Fluttershy was guided into a side room. From the looks of things, the room was used for extra seating space during the shop’s more busy hours. Upturned chairs hung off small round tables as the bright afternoon light leaked through drawn, checkered curtains.

“Are you excited to meet the others?” Mrs. Cake asked, closing the door behind them for added privacy.

“Uhm...yeah,” Fluttershy answered. Terrified and cautiously optimistic might have been more accurate.

“I just wanted to check with you one last time before you took the plunge. I know things can be nerve wracking for first timers,” Mrs. Cake consoled the pony.

“I s-should be fine,” Fluttershy replied.

“Well then there’s just one more thing, sweet pea,” Mrs. Cake said, wagging a pink diaper in the air, “I can’t have you going in there without a diaper on.”

Fluttershy felt a chill run down her spine as a rush of red filled her cheeks with a burning blush. It was embarrassing to see such a thing. It was exciting to see such a thing. Her mind drowned in conflicting emotions that clambered for dominance. She was amazed to finally be face to face with an actual adult foal diaper, but at the same time she feared even the thought of wearing one in front of Mrs. Cake. She felt fuzzy from gleeful giddiness, but tensed up with cold terror. Struck with awe, but at the same time, sick with worry. Enthusiastic, but nervous.

And to make matters worse, she was expected to wear a diaper in front of a room full of strangers. What if she was the only one wearing a diaper? What if they laughed at her? What if they called her names?

“Fluttershy, listen to me,” Mrs. Cake could see the thoughts rushing through the yellow pony’s mind. She could see the issues she was struggling with. If there was one thing she learned about Fluttershy during their tea time it was how conflicted she was about this whole thing. “There’s nothing to be scared about. I can understand you’re nervous, but trust me when I say you’ll enjoy yourself. The ponies inside are diapered as well and they won’t find it weird if you’re wearing one too.” She lifted Fluttershy’s slumped over head with a guiding hoof. Their eyes met with one another as hers twinkled with trust and sincerity. “I trust everypony attending this party will keep everything a secret and if you ever have any problems you can come and see me, alright?”

The beating in Fluttershy’s chest wouldn’t stop pounding against her chest, but the rhythm of her heart seemed farther away when she looked into Mrs. Cake’s eyes. The maternal mare was always so supportive of her, even when she admitted she liked wearing diapers. At no point in their relationship did the mare betray her trust or mislead her. What she was saying was truthful, Fluttershy understood that.

“O-okay, Mrs. Cake,” Fluttershy finally said with a nod.

“That’s my girl,” Mrs. Cake smiled, “then first things first, you’ll have to lay down on your back.”

With a large towel laid out on the ground, Fluttershy positioned herself squarely in the center of the warm fabric. Her back legs instinctively curled up to her chest in a long forgotten pose from her childhood that seemed like ages ago. She stared up at the ceiling where lights loomed overhead like beacons announcing what was to come. Such a position already felt so compromising.

“Now there are a couple rules I’d like to go over with you before we join the party,” Mrs. Cake started as she shook the diaper open with a wave of her hoof, “like I said, everypony else will be diapered, but we’re still adults here. So there’ll be no bullying, no rough housing, and absolutely no swearing.”

It was easy for Fluttershy to agree with the rules for now. All of them were pretty standard to keep mature ponies civil. She even had a lot of the same rules back at her cottage when dealing with animals and hardly any of them had a problem with upholding to those.

“The bathroom is off limits without adult supervision,” Mrs. Cake continued, lifting Fluttershy up by the ankles to slip the new diaper underneath, ”but you won’t have to worry about any of that. You’ll be using your diapers for all your needs.”

The rule hit Fluttershy just as her bottom lowered onto the open diaper, making a pink blush flood her face. In all this excitement she had completely forgotten that she might end up USING the diapers. There had been many nights where her mind would wander to that fantasy. To wear diapers and use them whenever the need crossed her mind. She didn’t have to think about it. All she had to do was let go and enjoy the comfort and security of a nice warm diaper. The crinkling softness of the diaper suddenly made it so real and exciting!

“I’ll be handling all the diaper changes for everypony, but if you ask extra nicely, somepony else may be able to help you as well,” Mrs. Cake continued, “but you are to never change your own diapers. Got it?”

Fluttershy blushed, but nodded. She felt kind of giddy agreeing to such things. It was like she was willingly giving up a part of her control.

This was actually happening. That much was made clear at this point. As the diaper was slowly pulled up between Fluttershy’s legs, a realization dawned on her that set everything into motion. This was really happening. She was being put into a diaper to play with other ponies in diapers. The very idea made her heartbeat quicken and her feathered wings shiver. She instinctively squeezed her thighs together in eager joy, noticing the diaper crinkling up a storm when she did.

“There we go! All done!” Mrs. Cake announced with a singy-song voice, holding up her forehooves in a bit of silly celebration. “Now you’re all set,” she said as she helped Fluttershy back to her feet, “just remember to come and get me if you need any help.”

Fluttershy only nodded as she felt like she was floating a little bit. The soft plushness that enveloped her waist tingled every inch of her powdered behind, like a fluffy cloud. She was nervous, but even in such a state of anxiety she couldn’t deny the wonderful feeling of finally wearing a diaper. In a way it was liberating to finally do it. All those years she spent dreaming and fantasizing about it she was finally hear, dressed up in a very thick diaper under the trusting care of Mrs. Cake. She was cautiously optimistic about what the future held now.

After the long anticipation, Mrs. Cake finally led Fluttershy into the front room where empty display counters and a cash register station waited, untouched on this quiet day. On any given day during the week this room was usually buzzing with activity as customers came and went, sampling the various sweets and cakes that the store had to offer. Today however it was unusually quiet with the rumblings of talking ponies permeating from the kitchen area that laid beyond. A hanging banner above the door read ‘Welcome Diaper Ponies!’ in fun, bright pink letters.

“Fluttershy?” a bright, cheerful voice exclaimed from across the room, making Fluttershy’s ears perk up with a worried slant. In bounced Pinkie Pie, clad in nothing but a diaper just like Fluttershy’s. ”Mrs. Cake said we had a new padded pony! But I didn’t know it was you! You like wearing diapers too?!”

“I-I was just curious,” Fluttershy shrunk a bit, hiding behind her mane of pink hair, “I never expected to see you here...”

“It was Pinkie Pie’s idea to throw these parties in the first place,” Mrs. Cake chimed in with a chuckle, “the eager filly couldn’t wait to make more friends into diapers as much as she was.” Pinkie beamed at the praise. “I’ll let Pinkie show you around. I’m never too far away if you need anything, alright Fluttershy?”

“Mhmm,” Fluttershy nodded before Mrs. Cake disappeared into the other room.

Pinkie Pie was absolutely ecstatic. “It’s sooo amazing that you like wearing diapers too!” she so loudly exclaimed, ”I always wondered, but never knew for sure!”

Fluttershy’s cheeks wouldn’t stop blushing, but she was happy to hear how enthusiastic Pinkie was about the whole thing. She didn’t laugh or tease like Fluttershy worried, and knowing she wasn’t the only one in diapers certainly made her feel better.

“Oh oh! Let me introduce you!” Pinkie exclaimed with a bounce, ”everyone else will be super duper excited to meet you!” Taking the shy pegasus by the hoof, Pinkie Pie pulled her friend into the other room.

On any typical day, the large tiled room was used as Sugarcube Corner’s kitchen area to bake and cook. However today, the place was completely transformed for the occasion. Kitchen utensils and cooking supplies were put away in tightly locked up cabinets and cupboards. Dangerous equipment was blocked off by large tarps and every window was covered up by foggy paper for added privacy. Any floor space that could was cleared for activities and was already populated with little activity stations like drawing, reading, and playing with age appropriate toys.

“Well let’s see...” Pinkie tapped her chin as she scanned the room. “Obviously you’ve met Mr. Cake. He was one of the first members!” She pointed over to the amber colored pony who wore a set of blue padded baby booties on his feet as well as a thick, white diaper around his waist. “Big Mac’s over there, but he seems to be busy with Mrs. Cake for the moment,” Pinkie Pie continued, now pointing to another part of the room where the big red stallion who appeared to be quietly scolded by Mrs. Cake. Although that was tough to tell from this distance. “Cream Hearts around here somewhere I think...and then...”

“F-Fluttershy?” a voice with an oddly familiar drawl called out from behind the pair, making the two turn around.

Before them stood Applejack clad in a light green, apple printed diaper. Her blonde mane was tied back with red ribbons into a pair of pig tails. She appeared just as awkwardly embarrassed to see Fluttershy as she was.

“O-oh...H-hey...Applejack...” Fluttershy muttered out, blushing as she looked away and fidgeted with her hooves some.

“I never thought you’d be...” Applejack spoke, clearing her throat of frogs as she tried to reorder her thoughts, ”I mean I never really thought about it, but...”

“It’s okay. I’m just here because I was curious,” Fluttershy fibbed, avoiding eye contact with the pony, “MMrs. Cake asked me to come...”

The two fell quiet after that, too awkward in each others company to say anything else. The silence was almost palatable and it took a happy gasp from Pinkie to finally break it.

“Bottles!” Pinkie Pie exclaimed in a fit of inspiration, “you two wait here! I’ll be right back with something to drink!”

The pink pony bounced out of the scene, leaving Fluttershy and Applejack alone in their awkward non-conversation. The two ponies stood awkwardly in each other’s company, hardly gathering the courage to look each other in the eye. For the next long, drawn out minute, the floor seemed to be a more acceptable alternative.

“I-I think I’ll go get something to eat,” Applejack finally broke the stalemate, hardly looking Fluttershy in the eye for more than a few seconds. “kinda hungry, ya know.”

“Yeah, that’s fine,” Fluttershy replied, “uhm, it was nice to see you.”

“Uhm yeah, y-you too,” Applejack said back before breaking away and waddling off.

Fluttershy felt herself shaken a bit off her foundation of calm. She came here nervous, but optimistic, however the chance encounter with Pinkie Pie and Applejack had left her not as sure as herself as Mrs. Cake had made her believe. Still, even then she couldn’t deny the comfort she felt knowing that two of her closest friends were into diapers. It was awkward to find out for sure, but maybe she’d learn to appreciate such a discovery.

“Heeere ya go!” Pinkie came bouncing back, a trio of big plastic bottles filled with milk balancing on her back. “Where did Applejack go?” she asked as she looked around.

“She said she was hungry,” Fluttershy answered, blushing at the size of the baby bottles.

“Hm, well I guess that means more milk for us!” Pinkie exclaimed, handing a bottle off to the blushing pegasus.

“Uhm, thank you,” Fluttershy answered, blushing as she held the bottle in her hooves.

The bottles were made of a thick, clear plastic with freshly warmed milk sloshing inside. Cute little decals of stars and rainbows decorated the outside with a soft nipple capping it off on top.

It took a few tentative minutes before she stopped staring at it, but eventually Fluttershy found the courage in herself to slip the bottle into her mouth to suckle on its rubber nipple. The milk was sweet and surprisingly delicious. She lowered to the ground alongside Pinkie Pie who was already on her back, legs wiggling in the air.

The pink pony seemed to play with the bottle more than anything, occupying her time with idly gumming the nipple while occasionally allowing the succulent milk dribble down her throat.

Nervous or not, Fluttershy was quite thirsty. She found that once she tasted some of the milk, her body didn’t seem to care where the nourishment was coming from. Perhaps the all the anxiety she had felt in anticipation to the party sapped her fluids. She hungerly suckled the milk down to quench her thirst. In record time she finished the bottle of milk. Pinkie Pie was hardly halfway done with hers when Fluttershy dropped the empty bottle off to the side. Finding herself unusually thirsty, she started working on her second bottle.

About half way through the second bottle, Fluttershy realized her eyes were bigger than her stomach. She was thirsty, but found the whole bottle and a half she drank to be sufficient enough. Not to mention she knew she needed to pee and drinking a bunch of milk certainly didn’t help that. She stopped to take a breath and possibly find a place to set the bottle aside for later.

“Mrs. Cake has a strict empty bottle rule,” Pinkie was quick to add, “if you start drinking one, you finish it.”

“B-but if I drink any more I-I might...” Fluttershy started to say before the bottle was popped back into her mouth by a swift moving pink hoof.

“Just relax and finish your bottle,” Pinkie chirped, happily returning to her own bottle. With an unconcerned fall backwards, she plopped back down onto her diapered seat, her bottle held high into the air as she suckled noiseily.

Fluttershy stood awkwardly beside her happy friend. She tried her best not to stare at Pinkie’s diapered butt which, admittingly, made the pink pony look adorable. She then turned her attention to her own bottle that annoyingly didn’t get any emptier in the last three minutes. She knew that if she drank the rest of the milk, she’d have no choice, but to pee in her diaper. If she finished her drink like Mrs. Cake’s rules clearly instructed her yo, she’d be flung face first further into this world of adult babies and diapers.

But she had to face reality. If she wanted to see what it was like then holding off the inevitable wasn’t an option. She had to do it eventually. And besides, Pinkie Pie looked so carefree in her diapers. She was so supportive and cheerful.

And so Fluttershy popped the rubber nipple into her mouth and began suckling down the warm milk. Sure enough her body responded in kind and began warning her of her already straining bladder. That urgency only got stronger and stronger the longer she ignored it. It started as a subtle pressure, then an aching pain, and before long she was wiggling in place all the while balancing the bottle in her mouth. Finally she just couldn't hold it anymore. Against her body's properly trained instincts she stopped dancing and continued sucking on her bottle. Her cheeks flared up a bright red, but she finally submitted, bowing her legs apart.

It started as a tiny leak, but in a short second Fluttershy was peeing into her diaper at full force. She bit down on the rubber nipple as a creeping warmth spread across the midsection of her diaper and leeched its way up both sides of the absorbent material. The diaper subtly swelled around her as it turned yellow and dark.

“Oh Mrs. Cake!” Pinkie called out in a singy song voice, “somepony needs a diapee change!”

Chapter Three

Fluttershy shrunk back as Mrs. Cake promptly answered the call. The motherly mare brought with her Big Mcintosh who was sporting a very very soggy diaper and a green pacifier. “Oh Fluttershy, did you have a little accident?” she cooed at the pegasus, running a hoof across the edge of the diaper to check herself, “well not to worry, me and little Macky were just about to go and get changed. Isn’t that right, Big Mac?”

The tall stallion just blushed, nodding meekly as he tried to avoid making eye contact with the other ponies. The apparent embarrassment only drew attention to his diaper, which was practically soaked through and through. It put Fluttershy’s meager ‘accident’ to shame.

“Come along then,” Mrs. Cake chirped with a beckoning hoof, “I’ll get you both changed while I’m at it. Pinkie if you could be so kind as to be mommy’s little helper.”

“Can do!” Pinkie exclaimed with a bounce.

With blush filled cheeks, Fluttershy was pulled up to her feet and nudged away from her spot on the floor. Pinkie Pie happily bounced behind the group as Mrs. Cake guided the two soggy ponies across the kitchen area where a side room could be seen.

Mrs. Cake, Fluttershy, Big Mcintosh, and now Pinkie all filed into a side room that connected itself to the storefront. It appeared to be some sort of living room or parlor. An auxiliary living space to entertain guests or quietly read a book. A couch in the middle served as the focal point of the room. Surrounding it were end tables on either side and a coffee table in front of it.

For today, everything was pushed to the side and the couch was pushed up against the far wall, opening a wide open space on the soft carpet for any number of activities. A large changing pad laid across the floor, large enough to comfortably fit two grown ponies on top of it. A nearby shelf contained a box of changing supplies as well as a stack or two of neatly folded diapers. It seemed that Mrs. Cake had planned this party out well and this was to be the designated diaper changing room. Such a concept made Fluttershy blush.

“Alright, sweet things, on your backs!” Mrs. Cake sang, nudging Fluttershy and Big Mcintosh forward toward the changing pad.

Mcintosh took the lead and waddled ahead of Fluttershy with his overly swollen diaper in tow. The urine soaked thing that hung on his waist sloshed and crinkled obnoxiously with every step he took. Fluttershy couldn't help but blush as she stared at the yellow stained garment. She could even smell the faint stench of urine emanating from it. A smell that fiercely competed for dominance with the stallion’s natural masculine musk.

“You too, Fluttershy. Can’t have Little Mac be the only one getting a diaper change. He’d get all embarrassed,” Mrs. Cake cooed as she pushed Fluttershy the rest of the way onto the mat, even going as far as to helping her lower herself onto her back.

The changing pad had a slight cushion to it and was made of a slick, waterproof material that crinkled under the two ponies’ weight. It chilled Fluttershy’s back as it made contact with her soft fur and made a tiny, shaky gasp slither out of her muzzle.

“There’s a good girl,” Mrs. Cake cooed as she lowered herself to the ground, “Pinkie, be a dear and grab me some supplies for the foals.”

“Okie dokie!” Pinkie cheered before bouncing over to the shelf and assembling the needed supplies.

“You’re first, soggy britches,” Mrs. Cake said to Big Mcintosh as she slid in between the stallion’s legs, “wait any longer and this thing might burst!”

Big Mcintosh obediently followed Mrs. Cake’s lead and spread his legs further apart as if this was all so routine. His yellow diaper ballooned outwards around his crotch, nearly dwarfing him in size.

Fluttershy couldn’t quite look away from the sexy stallion who laid beside her. In a weird way, the soaked diaper and pacifier made Big Mac look...more attractive wearing them. Maybe it was her own diaper that was enticing this thought. Maybe wearing a wet diaper was the least of her problems. Maybe she was staring at his diaper just a little too intently.

With showy flare, Mrs. Cake pulled away the diaper’s tapes, loosening the sodden thing around Big Mac’s waist. Surprisingly enough, opening the diaper revealed not a throbbing girth that Fluttershy fantasized about, but instead a bright blue hunk of plastic in the smoothed out shape of a softened member.

Pinkie Pie was quick to notice Fluttershy’s puzzlement. “Mrs. Cake makes all her stallions wear chastity cages so they behave,” she giggled, eyeing at Big Mac’s tightly bound up cock.

“Helps keep their hooves off their diapers too,” Mrs. Cake chuckled before grabbing at the cage and jiggling it, “isn’t that right, Little Macky?”

Big Mcintosh whimpered up a storm, but still found the strength to nod. His body was tensed up into knots as a desperate burn of desire flared up his cheeks. With his bound penis exposed out in the open, all he could do was squirm and let out muffled huffs behind his pacifier. His cock remained achingly soft behind the plastic restraints, occasionally throbbing painfully against the cage.

“D’aww, look at his little squirmies,” Mrs. Cake cooed as she popped open a plastic tub of baby wipes. “Maybe if you behave yourself, I’ll unlock you later."

Big Mcintosh whimpered some more, but nodded submissively. His cheeks still burned with a red heat, but outside of a fussy wiggle he did with his legs, he did nothing to voice his pent up frustrations.

“That’s a good boy,” Mrs. Cake cooed some more, “now let's get you cleaned up.”

Humming a calming little tune, Mrs. Cake cleaned Big Mac’s crotch with the cold scented wipes. The stale, pungent scent of urine was slowly replaced with the gentle and fresh smell of cucumber and melon. One by one the used wipes were all gathered into a little pile in the middle of the open diaper before it was all wrapped up into a tight ball.

A new diaper was fanned out in the air with showy flare before being effortlessly slid underneath the stallion’s butt. Mrs. Cake hiked Mcintosh’s legs up into the air, possibly longer than she needed to, before slowly lowering them back down with the diaper in place.

Next step was the baby powder which emanated a soft, flowery scent. The white powder was so delicately sprinkled onto Mcintosh’s crotch before being lovingly rubbed in by Mrs. Cake’s caring hoof. She even made sure to give his firm rump a generous powdering and finally gave his belly a little sprinkling before pulling the whole diaper up between his legs.

The end result was a crisp and expertly taped diaper that was not too tight and not too loose. Big Mcintosh fussed a little more as his bound up member was once again covered up by a diaper, but behaved himself. Mrs. Cake finished the diaper change with a gentle tummy rub that turned the stallion’s fussy scowl into a happy smile.

“There’s a good boy,” Mrs. Cake cooed before sliding her way down the bench and in between Fluttershy’s legs. “Okay Fluttershy, now you,” she said as she rubbed her tummy, “such a good girl being so patient!”

A shy smile grew across Fluttershy’s face as she blushed at the lovely treatment she was receiving. Continuing her humming tune, Mrs. Cake so casually ripped the tapes off of Fluttershy’s diaper, releasing the pegasus of the muggy warmth that surrounded her crotch. A rush of cold air flooded the inside of the diaper, making Fluttershy shiver weakly.

Fluttershy was much too embarrassed to even look the motherly mare in the eye and Mrs. Cake seemed to pick up on that. Despite all the fun she had with Big Mac, Mrs. Cake changed Fluttershy in an oddly routine manner. With no sexual subtext or theatrical flare, she had the old diaper pulled out from under Fluttershy, wiped her clean, slipped a new diaper under her, and powdered the area liberally without losing a beat of the rhythm. It was a task she had done a dozen times today already and it showed.

Hiding her blush covered face behind her forehooves, Fluttershy allowed her body to be manipulated and moved about as the old, heavy diaper was pulled away and replaced with a fresh, fluffy diaper. As exciting - and perhaps erotic - as it was to watch Big Mcintosh getting his diaper changed, the humiliation of being in such a submissive position made her feel much too vulnerable to enjoy it. She felt put on the spot, yet strangely comforted by how tenderly Mrs. Cake handled it all. She felt like everypony was watching her, yet

Before she knew it, the diaper change was over and she found herself wrapped in a freshly powdered and incredibly soft diaper. Spending so long in a soggy diaper almost made her forget how euphoric a fresh diaper felt. It was like she was being hugged by a cloud.

“There we go! That wasn’t so hard, was it?” Mrs. Cake said so softly as Fluttershy bravely peaked out from behind her hooves at the end of it all.

Big Mcintosh was already back on his feet, stretching a tiny bit as the stiff material of the fresh diaper softened up and molded around his toned backside. Fluttershy’s attention slowly shifted over to the masculine stallion as she watched him waddle around the room and exchange a couple whispered words with Pinkie Pie.

“Up we go!” Mrs. Cake exclaimed, taking Fluttershy by the hooves and helping her up.

“Wasn’t that the funnest!?” Pinkie exclaimed as she bounced over to the pair, “diaper changes are the BEST!”

“Speaking of diaper changes,” Mrs. Cake said, now running a hoof across Pinkie’s diapered crotch. “Hm, only a little wet,” she mused mostly to herself, “we can probably wait till after snack time, hm?”

“Might need a bath after snack time,” Pinkie Pie giggled playfully with a little blush in her cheeks.

“Well, we’ll cross that bridge when we get to it,” Mrs. Cake nodded before turning to the other two. “Alright, off you go, my little ponies! It’s almost snack time!” She encouraged the group of diaper ponies out with a couple pats on the butt.

Chapter Four

With a trail of baby powder following them out, Mrs. Cake led the group back into the kitchen area. Fluttershy straggled behind the group, still trying to get use to the fresh diaper between her legs. The fact that not ten minutes ago, she was carrying around a heavy and wet diaper between her legs like some kind of careless toddler only made the dry diaper feel that much more satisfying. Now she had a fluffy scent to her fur and walked with a subtle bounce. It was like she was floating a little bit. In a funny way, the diaper change, now that she had some time to digest the sensations, was a flattering experience.

Carrot Cake and the other ponies were already hard at work assembling a snacking area, gathering food and drink, cleaning off counter space, and ensuring everypony had a place to sit. A round, stout plastic table was placed in the middle of the area, set with three plastic plates and bulky, brightly colored plasticware. Not five feet away from the table stood three highchairs of various designs, all lined up in a nice neat row.

With the occasional butt pat to encourage the diapered ponies along the way, Mrs. Cake ushered her three charges straight over to the highchairs. Pinkie Pie enthusiastically clambered up into one of the chairs without being told. She opted for the yellow one that was decorated with candy stickers and was strategically the closest to the table where a number of snacks were already being laid out. She wiggled into the inset plastic seat that fit comfortably around the curve of her padded butt, hungrily eyeing the delicious spread of food.

Mcintosh, although quiet and much less enthusiastic about the decision, shyly asked for a highchair as well. However he waited for Mrs. Cake's lead before he even neared the row of chairs. Smiling at the bashful stallion, Mrs. Cake was more than happy to help him into a chair of her choice. Much to Big Mac's embarrassment, she guided him towards the high chair in the middle, a pink one with girly flowers painted all over its plastic face.

Once the two ponies were comfortable, Mrs. Cake helped them into a pair of buckling shoulder straps that hung off the back of the highchairs for added security. The straps clicked with plastic buckles in the front, ensuring a tight fit. Matching plastic trays were then slid into place over the two ponies' laps, locking on either side with the help of metal rails.

“Alright, Fluttershy, up you go!” Mrs. Cake chirped, as she gestured towards the remaining highchair, a blue one with cloud stickers.

Fluttershy’s face flared up as she shrunk back a tiny bit. This whole time she had watched the other two get strapped into adult sized highchairs and at no point did she even think that she'd be joining them. She never imagined she’d be in such a position. To sit there out in the open like that with everypony staring. Could she really let herself become locked in like that?

"B-b-but I..." Fluttershy was lost of words.

"D'aww, are we a little scared of the highchair?" Mrs. Cake cooed with a warm smile, "tell you what, just for you, I won't strap you in. Alright? They're just there to keep someponies from getting into trouble." the older mare threw a glance over at Pinkie and Mcintosh who giggled and blushed respectively. “Now up you go,” she said, extending a helping hoof.

With the caring guidance of Mrs. Cake, Fluttershy felt a little more confident in her choice. She climbed into the highchair’s plastic seat which, given the bulk of her diaper, was actually quite the challenge for the not-so-dexterous pegasus.

Out from a nearby drawer Mrs. Cake pulled three bibs that appeared to be enlarged versions of actual baby bibs. Their designs were soft and pastel, consisting of stitched on patterns and friendly little pictures. Fluttershy was given first pick. Or at least she would have if Mrs. Cake didn’t automatically assume she was much too little to make such big decisions and pick for her instead. She was given a soft pink bib with an adorable repeating bunny pattern running across its surface. Mcintosh had a green one with a big red apple stitched to the front tied around his neck. And lastly Pinkie Pie was given a bright red bib with a big balloon stitched on the front. Although it was a bit difficult to get the bib tied around the bouncing pony’s neck.

Applejack, Carrot Cake, and a third pony - which Fluttershy assumed was Cream Heart - all found their places around the table. The three ponies had sample platters fit for a toddler to eat from, giving them a wide selection of slices of fruit, cuts of carrots and celery, as well as a pile of animal crackers. The three ponies in the highchairs, on the other hand, were given a premade plate of fruit, crackers, and applesauce all served on brightly colored, segmented food trays.

Hungry and hardly able to resist the delicious spread that was laid before her, Pinkie Pie chose to feed herself, albeit messily and without a spoon. She handled the meal like an excitable toddler, using her hooves as an inefficient means to carry the sloppy food into her mouth.

Meanwhile Mrs. Cake took on the task of feeding both Mcintosh and Fluttershy simultaneously. A daunting task to any other pony, it was easily handled by the experienced mother. With the patience of a saint, she scooped mouthful after mouthful of the ponies’ food, shoving it into their mouths only when they were ready for it. Fluttershy was understandably hesitant about being fed in such a way, but Mcintosh as well had to work past some blushing embarrassment to be fed as well.

Fluttershy found the food surprisingly sweet and decadent. Maybe it was the whole experience of being fed from a highchair or maybe Mrs. Cake’s loving hoof added extra sweetness to the food. The fruits tasted fresh while the crackers could have very likely had some frosting on them. Every mouthful made the diapered pegasus feel...tingly. She couldn’t quite describe it. It made her happy, fuzzy, and a little bit squirmy. She was beginning to enjoy herself!

Big Mcintosh, despite his larger stature and perceived maturity, seemed to struggle the most with being fed by somepony else. He spent the entire time hunching so that Mrs. Cake could reach his mouth with her short reach. No matter how careful he tried to be with eating as neatly as possible, the motherly mare seemed to go out of her way to ‘accidentally’ miss his mouth a tiny bit, resulting in a little bit of food not making it in completely. He continued to blush as he fruitlessly craned his head around the spoon.

All the while Pinkie Pie reveled in her delicious meal. In that short amount of time, the cheery pony managed to get her bib almost completely covered in all manners of brightly colored splotches. Her face and hooves were just as messy and was sticky to the touch. Still she continued to eat or, more accurately, play as she worked through her food like a mischievous child. Crumbs and fruit mush covered her food tray as the meal went on.

Suddenly Pinkie Pie’s spirited and hyperactive bouncing grinded to a halt, catching Fluttershy’s attention as she watched her friend from the corner of her eye. She watched as the pink pony began to hunch over in her seat, gripping the edge of her highchair tray with her sticky, food covered hooves. Her eyes slammed shut, her face scrunched up, and for an uncharistic moment, Pinkie fell absolutely silent.

It was difficult to understand what was happening from Fluttershy’s position. Between spoonfuls she could see Pinkie Pie curling up in her seat and leaning forward a tiny bit. The pink pony grew red in the face as she took in large breaths of air. She’d breath in, pull herself forward in her seat, and bear down on her scrunched up body.

After Fluttershy watched for a little bit more, Pinkie Pie’s body language began to look familiar. She recognized the very same body language from when she occasionally babysat the cake twins. But...she couldn’t really be doing...doing that, could she? There was a part of Fluttershy that thought it impossible. Seeing Pinkie Pie in a diaper and acting like a silly foal was one thing, but seeing her do...that? Impossible?

Shamelessly, Pinkie Pie continued to grunt and scrunch up her red face. Once she finished, she returned to playing with her food like nothing had happened. It appeared that whatever happened had passed and that she wouldn’t be telling Mrs. Cake about it any time soon.

Mrs. Cake however, needed no signalling. In fact, once Pinkie Pie finished, the motherly mare was watching from her spot in front of the other two diapered ponies as the pink pony uncoiled her body and slowly leaned back in her seat with a squirming wiggle of her legs. The two seemed to have an understanding. No words were exchanged between the two, only looks. Mrs. Cake started by loudly sniffing the air, following a rather rank smell that permeated past the scent of apples and baby powder. She followed it over to Pinkie who bounced less and wore a giggling, bashful grin. Their eyes met as Pinkie shrunk back in her seat and blushed a deep pink.

Pinkie Pie was then helped out of her highchair as the foul odor followed her. From the back, Fluttershy could easily see a sizable and heavy lump in the back of her friend’s diaper, making her eyes grow wide and her face flare up once she put two and two together.

As if she really needed to, Mrs. Cake pulled out the back of Pinkie’s diaper and peeked inside. “Just as I thought,” she finally announced, letting the elastic waist snap back into place, “we got a stinky bottom here!”

Instead of being embarrassed about soiling herself - or mortified in Fluttershy’s case - Pinkie took it all in stride and beamed proudly at what she had done. She didn’t hide her sagging diaper, she flaunted it and wore it like a badge of honor. There was a spring in her step and she seemed to really enjoy being made a spectacle out of.

“Let’s get your diaper changed, little lady,” Mrs. Cake commanded, patting Pinkie on butt.

Fluttershy looked away from the whole thing before it was too late. It took her a moment or two to realize she had been staring quite intently at Pinkie’s well used diaper through the whole scene that played out in front of her. She gulped hard as her eyes snapped back to her tray of food. From the corner of her eye, Fluttershy watched Mrs. Cake guide Pinkie Pie back to the changing room as the pink pony trotted with an incredibly exaggerated waddle.

“Here, honey, let me help you with that,” a new pony swooped in and grabbed Fluttershy’s spoon, wasting no time at scooping up another helping of apple sauce. The new pony was a tan colored mare with a bronze brown mane. She wore a soft pink diaper around her waist that partially obscured her cutie mark consisting of a baby bottle of milk and a pink heart.

“U-uhm, th-thank you,” Fluttershy shrunk back as her face flared up a deep red. She suddenly lost all of her freshly gained confidence talking to this new pony.

“Oh silly me, my name’s Cream Heart,” the new pony said, holding out a hoof to shake to which Fluttershy so cautiously shook after a few moments of hesitation. “Sometimes I help Mrs. Cake with caretaking duty,“ she continued to explain, “she seems to always have her hooves full with a room full of foals to look after.”

“But you’re wearing a...a diaper,” Fluttershy pointed out.

“Not everypony who wears diapers are babies, Fluttershy,” Cream Hearts winked, “caretakers know how to have fun too! Now be a good girl and open up. Here comes the zeppelin!" she sang as she swooped in with another spoonful of food. Tentatively, Fluttershy opened her mouth and swallowed whatever mixture of applesauce and fruit Cream Heart gave her. "Good girl!" Cream Heart celebrated, scooping up another mouthful of food.

Meanwhile Big Mcintosh was stuck unattended in his chair. His half empty tray of food sat untouched in front of him as he bashfully glanced over to Fluttershy and Cream Heart.

Being the well experienced caretaker that she was, Cream Heart took notice of the shy stallion. “Come on, Little Machy," she said, "you haven't touched your apple sauce."

"B-but Mrs. Cake usually..." Big Mac spoke with a small, shy voice, letting his excuse disappear into a barely audible whisper.

"I know you like being a big baby and letting somepony else feed you, but I'm busy feeding little Fluttershy here," Cream Heart answered, scooping up another helping of food, "can you be a good little colt and show me how a big boy eats?"

Mcintosh shrunk back in his seat, letting out a submitting sigh as he looked down at his tray of food. A half handful of carrot sticks, a small pile of apple sauce, too much to leave on the plate and waste. He knew better than to be so wasteful. So reluctantly, he picked up his big plastic spoon and finished his meal in the most grown up way one could while sitting in a giant high chair while wearing a diaper. He quickly found the bulky spoon quite a chore to handle, often dribbling a tiny bit of food out of his mouth despite his most careful attempts.

"Such a big boy!" Cream Heart exclaimed with a coo when she was there to wipe Mcintosh's face with a dry part of his bib.

Cream Heart sat between the two diapered ponies and helped both of them with their meal, but seemed to focus more of her time on Fluttershy. And despite being meek and shy about the whole thing, Fluttershy warmed up to the new caretaker and began to appreciate the helping hoof. The mare was certainly a qualified and skillful caretaker, juggling the two needy ponies with ease. Whenever Fluttershy was ready for another spoonful of food, Cream Heart was always right there ready for her and when Mcintosh got a little too antsy and fussy in his seat, she was always there to quiet him down and remind him to behave himself.

In the end, Fluttershy was fed her meal with little to no food messing up her bib. Big Mac, on the other hand, had a few near misses while trying to feed himself as neatly as possible. This lead to a few, albeit large and obvious, splotches on his white bib.

“All gone!” Cream Heart chirped, wiping Fluttershy’s muzzle clean with her bib. She then turned to Macintosh who slumped in his seat with embarrassment. “Guess we know who the bigger baby is,” Cream Heart winked, making Fluttershy stifle a little giggle.

As snack time was drawing to a close, the group of ponies slowly gravitated away from the kitchen area and off to the various play stations that were set up in other sections of the room. Fluttershy and Mcintosh, after being thoroughly cleaned up by the maternal Cream Heart, was helped out of their chairs and guided over to a large playmat where a crate of toys waited for them.

"Now you two play nice," Cream Heart said as she gently nudged the two ponies down to the padded ground. "I'm going to go check on Pinkie and Mrs. Cake."

Chapter Five

It was times like this that Fluttershy really wished she had an instruction manual for playtime. Everypony around her seemed to grab whatever colorful, plasticky toy they could find and played with it with such carefree bliss. She watched as the handful of ponies involved themselves in acts of pretend and impromptu tea parties. No words were exchanged or thorough explanations on what kind of game they were playing, everyone just seemed to...play. And in the middle of all that fun, Mcintosh and her sat quietly on a playmat with the toys around them going untouched and unplayed with.

She was certainly not going to make the first move. She didn’t even know where to begin. Wooden blocks and animal plushies dotted the floor around them and all she could worry about was making the wrong move. What if she picked up the wrong toy? What if she grabbed somepony else’s toy and they yelled at her? What if she messed up? What if she started playing with a toy that wasn’t deemed ‘age appropriate’? Was she a toddler or more of a baby? Did any of that matter? Did nothing matter? Did everything matter?

After an awkward pause, Mcintosh finally reached for a train set that sat on top of the pile of toys. Made primarily of wood, the toy was a chain of simplified train cars that connected to each other by little magnets on their ends. The simple plastic wheels struggled to navigate the cloth top of the foam playmat as he rolled it back and forth in front of him.

Fluttershy scooched closer to the playing stallion, sensing an unspoken obligation she had to fulfill. She still had no idea what she was going to do or what toy she was going to play with, but seeing the stallion fumble with the bulky toys sparked the helpful pony in her. She had to do something so he wouldn’t feel so left out.

No words were spoken between the two blushing ponies. They barely even made eye contact with each other realizing that was just too embarrassing to do. Fluttershy realized it was just like playing with her little animal friends back home. Maybe she was just over thinking all this and all she had to do to enjoy herself was to do what came naturally.

Mcintosh certainly seemed to warm up to her as they played. Or at the very least, his shoulders seemed less tense. Like Fluttershy, the stallion still blushed and bashfully avoided eye contact, but it was clear that he enjoyed the little playtime, despite the awkwardness. It was all going along so well until he suddenly acquired a worried look on his face. For a moment the blush in his cheeks drained, leaving a pale mask of panic as his eyes darted around the room. Without another word he carefully stood up as if he was cradling a basket of eggs on his back.

Confused, Fluttershy watched as the diapered stallion waddle over to Cream Heart who was cleaning up after the ponies’ mealtime. They exchanged words for a minute before Cream Heart shook her head and pointed back at the playmat. Whatever she said caused the stallion to slump forward with his ears lying flat on his head. Mcintosh didn’t say another word as he waddled back to the playmat, defeated. If anything he said even less than before and now appeared more rigid. He tried his best to act casual, returning to play as best as he could while not moving from his spot on the mat as much. Every slight shift he made was coupled with a pained wince and a worried look around the room. He was growing anxious about something and Fluttershy blushed to think what that could be.

“I’m back, sweet rolls!” Mrs. Cake chirped as she appeared trotting over to the pair. She had an invigorated spring in her step, “Mrs. Heart said you had something to tell me, Little Macky?”

Big Mcintosh threw a glance over at Fluttershy before quietly shrinking back as he mumbled something.

“What’s that, Little Macky?” Mrs. Cake announced, leaning over the stallion with an overly enthusiastic pose, “I can hardly hear you.”

“I-I need to uhm...G-go...” he replied with a meek and bashful voice.

“Go where, little one?” Mrs. Cake replied, she wasn’t letting him off so easily.

“T-to the bathroom...” he said, before correcting his vocabulary, “p-potty...”

“Oh I see, what a big boy asking to go potty!” the motherly mare cooed with a pat of the stallion’s head, “I have to check up on everypony else before I can take you there. Can you hold it for a little while?”

“Y-yeah...” Mcintosh gulped.

Carefully and continuing to wince every now and then, Big Mcintosh pulled himself up to his feet and followed Mrs. Cake as she trotted off to tend to the other ponies. He followed her around like a timid puppy, nearly nipping at the mare’s ankles as his back thighs squeezed tightly together. His large diapered bottom wagged behind him as his face curled up in discomfort. Things were starting to get dire and he silently wished for Mrs. Cake to hurry up.

And Mrs. Cake certainly didn’t make it easy for him. She made her rounds slowly and deliberately, frequently stopping to make small talk with the other ponies as the tall stallion whimpered and squirmed behind him. On the surface it appeared that she was just being a good host, but the smirking glance she would throw behind her at the stallion hinted at a more mischievous angle. Still Mcintosh tried to hold on as much as he could.

Fluttershy meanwhile tried her best to play alone, but now found her attention trailing elsewhere. Her gaze gravitated away from the pile of toys in front of her and toward Mcintosh who grew more and more tense as the minutes went on. She watched as his body language turned from rushed fidgeting, to slow and painful steps, nearing dangerously close to the edge of losing control.

Finally the pain was just too great, and Mcintosh stopped dead in his tracks as Mrs. Cake was just finishing up a delightful conversation with Pinkie Pie about their favorite colors of spring. He groaned lowly as his cropped tail began to rise. His back legs splayed out in a crouch as his head lowered to the cold tiled floor. For those observant few who were quick to notice, Mcintosh’s diapered rump could be seen rising into the air as his body tightened with involuntary muscle cramps.

Fluttershy watched the whole thing, wide eyed and breath shallowed. From her spot on the floor, she saw Mcintosh’s diaper slowly expand in the back and become heavier with each tightened squeeze of the stallion’s straining stomach. A hefty weight pulled his diaper down with an unmistakable lump sagging low between his legs. She watched as he buried his face behind his front legs in a weak attempt to muffle his involuntary grunts.

The tall stallion was stuck where he stood, frozen in the compromising position for all to see. When he did finally finished up after what felt like hours, he slowly pulled himself up, his face burning with shame. He stood up to see Mrs. Cake staring back at him with a disappointed tap of her hoof.

"And here Cream Heart was telling me how much of a big boy you were acting during snack time." She spoke loudly and dramatically, making sure to project her voice like an actress on a stage, “well judging by that BIG, MESSY diaper, I see she was wrong.”

There were a few giggles heard around the room, some affectionate ‘aww’s, and some ponies didn’t even look up because of how common a grown stallion in a messy diaper was at parties like these. Whatever their reaction, Mcintosh held his head low, far too embarrassed to even look Mrs. Cake in the eye. He had half a mind to speak up in protest and boast that he was a big boy, but those words only came out as pathetic little whimpers.

By the grip of his mane, Mrs. Cake tugged the stinky stallion away from the scene and headed straight for the changing room. However just before heading over there, she made a quick stop over at Fluttershy’s play area where the quiet pegasus continued to stare at the stallion’s hefty diaper.

“Fluttershy, would you mind being my little helper while I change Little Macky?” she asked.

Startled at first, no words could form themselves in Fluttershy’s mouth. She could only give the motherly mare a meek nod as she slowly stood up. Mcintosh continued staring at the ground, too humiliated to look up. It was tough to tell who blushed the hardest.

Once again, Fluttershy found herself back in the changing room. The ever present smell of baby powder now competed with the stench of old diapers as the festivities outside continued throughout the day. She watched with bated breath as Mcintosh rolled onto his back, taking great pains to avoid lying directly on top of his lumpy diaper. Her chest continued to flutter as she savored the seconds of watching the adorable diapered stallion fuss over such a tiny thing. She paid especially close attention to the sizable lump that formed around his backside, a sight she didn’t notice she was staring at until Mrs. Cake intervened.

"Hold this, sweet roll," Mrs. Cake said as she handed Fluttershy a new diaper, "and don't lose it now. We just might have to keep the big stinker in his messy diapers if we don't have a fresh one for him!"

Fluttershy stole a shaky inward gasp as her grip tightened around the folded diaper. Forcing Mcintosh to wallow in his messy diaper for a little longer if she lost the diaper? That would have been terribly awful, right? Right? No matter how unlikely losing something as big as an adult sized diaper, she couldn’t help but wonder if she did just that. She didn’t want that to happen, right?

“Oh shoot, have we really gone through another tub of wipes?” Mrs. Cake said tsking as she looked around the room, “you two sit tight while I go fetch another pack!”

Without another second to react, Mrs. Cake trotted out of the room, leaving the two diapered ponies alone. They sat in silence, awkwardly trying to avoid staring at each other. The subtle stench of Mcintosh’s messy diaper began to mingle with the ever present scents of baby powder and floral scented lotion. She never quite felt this way before. It was like fawning over an adorable baby animal mixed with falling in love with a handsome lover. It was innocent yet...incredibly erotic. And it all felt mutual.

“Sorry for the...smell,” Mcintosh finally spoke, breaking the heavy silence.

“O-oh, no no, it’s quite alright. I-I don’t mind, really,” Fluttershy answered with a stammer, hugging the folded diaper tightly. “Y-you uhm...do this often?” she then asked with a small voice. A voice so small that if she decided to fall back from the question she could easily brush it off with a quick ‘nevermind, it was nothing.’

“O-only when I’m able to,” Mcintosh answered after a long, embarrassing pause. Fluttershy’s ears tingled with red. Looks like he heard her after all. “Mrs. Cake only throws these...sort of things every couple of months...”

“A-and you always...wear?” Fluttershy dared another question, again in the same small voice.

“M-mhmm,” the stallion bashfully replied.

“A-and...use them?” Fluttershy almost sounded a bit excited as she spoke, eyeing the lump in Mcintosh’s diaper, “...like this?”

“I-I...like how it all feels...” he answered, sharing a similar hint of nervous excitement, “a-and I like...being treated like...this...”

“S-so having an accident in front of Mrs. Cake?” Fluttershy asked, her grip on the new diaper tightening, “i-it was just an act?”

“Sorta... Sh-she knows that I enjoy it...”

“A-and the...cage?” Fluttershy finally asked, noticing Mcintosh tense up at the mere mention of his chastity, “you like that too?”

“I-it makes Mrs. Cake happy to have it on to hold it over me,” he answered, not really being all too pleased about it.

Of course, Fluttershy assumed anything that prevented any stallion from just...touching themselves whenever they felt like it might have been bothersome. Although to have that special bit of pleasure locked away and held over him like a carrot on a string had some special allure to it. “Does she ever unlock you or...”

“O-only if I’m good...”

“Oh...” was Fluttershy’s response, followed by a long awkward pause as she blushed at the ground, “I-I think...I think you look really cute when you uhm...use your diapers...”

“Th-thanks...” Mcintosh said back with a surprisingly meek voice, “I-I think you look cute using your diapers too...”

"I'm back!" Mrs. Cake said in a singing voice as she slid back into the room with wipes in tow. "Sorry little Macky, it seems all we have left are lavender scented wipes. Mcintosh didn’t seem to mind. In fact, he seemed to smile a tiny bit at the embarrassing thought of smelling so girly.

Mrs. Cake went right to work on the diaper change by casually ripping off the four tapes that strained to keep the whole swollen thing wrapped around Mcintosh’s waist. Fluttershy stood by her side, diaper at the ready as she nervously squeezed the fresh diaper in her arms.

Even tucked away inside the plastic cage, the stallion’s well endowed girth looked so...big. It was no surprise he’d need such big diapers, Fluttershy thought to herself, big diapers for big babies. Maybe it was for the best to have his member locked safely away. He seemed so submissive and eager to please with the cage on. It was cute to think that everything he did, every good deed he performed, was an adorable attempt at winning Mrs. Cake’s favor so that she would grant him freedom from his chastity.

If it were up to Fluttershy, she probably wouldn’t have been won over so easily. At least that’s what she tried to convince herself of. She was starting to enjoy this little game. To have an obedient and strapping stallion eager to do whatever she asked him to. To humiliate him and tote him around like a trophy.

She could feel her face tingle and blush at the thought of it all. It was silly in a kind of way. To have her, meek little Fluttershy, lording over tough and stoic Mcintosh. It made her feel silly just thinking about it. Silly like a schoolgirl.

“Thank you for keeping a good eye on this, honey,” Mrs. Cake cooed, grabbing the diaper out of Fluttershy’s hooves and snapping the daydreaming pegasus out of her daze. “You’ve been very helpful so far. Maybe you can be my little helper for the rest of the day!”

She was kidding of course, but Fluttershy couldn’t imagine how many diapers Mrs. Cake had to change during one of these parties. And they were adult sized diapers too! Fluttershy could see herself changing a couple diapers, maybe, but being the sole diaper changer in a group of ponies who like spending their days drooling over themselves and acting like foals? She wasn’t sure she was ready for that sort of pressure.

“Hold this for a second, would you dear?” Mrs. Cake said as she hefted up the neatly rolled up diaper.

Not wanting to upset her host, Fluttershy quickly took hold of the diaper without fully realizing what she was holding. She immediately noticed a difference in weight between the freshly folded diaper and the old, well used one. There was a surprising amount of warmth coming from it. And the most subtle, earthy scents mixed with baby powder and lavender. Imagine just moments ago this big heavy thing was taped snuggly around Mcintosh’s waist as he waddled around, wagging his cute little bottom. She was starting to feel all tingly and silly again.

The rest of the diaper change passed like a dream as Fluttershy watched it in a half awake haze. Her mind still swam with silly little fantasies. Some possible, some impossible. Some innocent, some... not so innocent. It was tough to keep track of all these thoughts as the daydreams went into overdrive.

“Thank you for keeping an eye on that for us, honey,” Mrs. Cake chirped before turning to Big Mac who was now standing up freshly pampered, “well stinky britches, since you made the mess, you can throw it away.”

Big Mcintosh lowered his head shamefully as his embarrassingly messy diaper was handed off to him. He could only manage a very bashful glance over at Fluttershy who could only gulp quietly to herself as her face flared up. With a cloud of baby powder following him, he started to waddle off to the nearby diaper pail, which was already half full from the other party guests.

“No no, not here,” Mrs. Cake waved Big Mac off, “take that big icky thing out to the dumpster. I won’t have it stink up the place.”

The stallion gulped as his ears drooped. He whimpered something faint and squeaky in protest, but reluctantly waddled out the door with messy diaper in hand.

“I can clean up the rest of the mess, Fluttershy,” Mrs. Cake said, patting Fluttershy on the head, “you waddle on back to the party now, alright?”

“A-alright,” Fluttershy answered with a hasty nod. She skittered on out of the room as Mrs. Cake gave her an encouraging pat on the diaper. Even after the blush faded, Fluttershy felt all aflutter. She didn’t think her face would ever stop tingling.

Over by the other side of the room, Big Mcintosh stood at the back door, with his brown tinted diaper still firmly in hand. In a rare sight of things, he appeared nervous, fearful about stepping foot outside. Fluttershy could only imagine what was going through the worried stallion’s head. But at the same time she could only imagine how things would have been if she was the one giving him the orders. To have Big Mac whimpering up a storm and whining to her that he didn’t want to be seen outside wearing a diaper. To have her firmly telling him to do as she says or he’d get punished.

She shook her head out of yet another daydream before ponies started noticing she was staring off into space. There she went, feeling silly again.

Chapter Six

"Oh oh! Fluttershy! Over here!" Pinkie Pie called from across the room waving two enthusiastic, paint splotched hooves in the air.

The pink pony had situated herself back at the snack table that was now set up as an arts and crafts station. A disposable clear plastic sheet covered the top of the table to catch any spills or messes that would inevitably occur. A painting station was set up with a rainbow of hoof paint pots and a big stack of construction paper. Pinkie Pie wore a clear plastic apron that was already covered in paint smears.

Projects from earlier in the day laid scattered across the table, mostly consisting of sloppy hoof paintings depicting a wide range of colorful scenes like smiling flower fields and abstract streaks of colors. If Fluttershy didn’t know any better, the quick and carefree style of all the art almost looked like that of a toddler’s. It looked like the other party guests, not to mention Pinkie Pie, was really getting into the proper artistic mindset.

“Come paint with me!” the pink pony bounced, “c’mon, it’ll be fun!”

“You’re here painting alone?”

“Applejack was over here a little bit ago, but she had to leave early,” Pinkie explained, “something about a farm emergency.”

“Emergency?” Fluttershy repeated, but was quick to notice Macintosh was still here, only just now returning from the dumpster outside with a face filled to the brim with blush. Surely if it was an emergency at the farm they would both be needed, right? “I hope she didn’t leave because of me...”

“Because of you?” Pinkie replied, “Fluttershy, Applejack was super duper ECSTATIC that you were into this stuff! She just has a tough time showing it.”

“I guess it runs in the family,” Fluttershy replied.

“Sometimes life just gets in the way,” Pinkie added, “now come on! I have a spot saved for you right next to me and I got ALL the paint colors!”

True to Pinkie’s word, Fluttershy had a spot to call her own among the paint pots and loose sheets of paper. She wrapped herself in her own plastic apron and nestled in comfortably next to Pinkie.

Now painting was something that came to Fluttershy a little easier than playing with foal toys. While she felt silly trying to play games of pretend with bulky wooden trains, painting was something she enjoyed on her own time. In fact, she had an easel and a set of artisan paint brushes back at home. The large pots of colorful hoof paints that laid out before her were a far cry from her set up at home, but they were enough to spark her creative drive. Pinkie’s company also helped in that regard, allowing Fluttershy to relax better into the role.

Fluttershy liked drawing animals and nature scenes. She tried her best to capture the cutest animal friends she had waiting back home as best as she could with the hoof paint medium. She especially liked drawing rainbow colored bunnies that frolicked among splotchy fields of grass. Most of her drawings turned out a little simplistic, but the freedom to paint whatever she wanted helped her capture a childlike enthusiasm she had for the task.

Pinkie meanwhile didn’t seem to wait for any sort of ideas or inspiration to strike her. She instead just enjoyed painting and creating art with her friend. Some were quick, monochromatic smears of paint that slashed the colorful construction paper into mismatching halves. Others appeared to be an attempt at fitting as many colors as she could onto one picture. The excitable pony would bounce in her seat, giggling up a storm as she played with the hoof paints more than she actually painted with them.

By the time Mrs. Cake came in to check on the pair, the two diapered ponies had conjured up dozens of cute paintings in a creative flurry. Smears of hoof paint tangled in their manes as splatters of the rainbow of pigments streaked across their aprons and hooves. Not to mention leaving the crafts table in a rather chaotic state.

"Oh look at this mess!" Mrs. Cake chuckled. “You girls have been busy.”

“Lookit what we made!” Pinkie exclaimed, holding up her latest piece of work: a series of blue circles with speckles of yellow on them.

“That looks wonderful, Pinkie!” Mrs. Cake applauded, “and Fluttershy, I see you made some as well. Wonderful job!”

There was a flutter of excitement in Fluttershy’s chest when Mrs. Cake praised their hard work. She looked over her collection of splatters and oblong shapes with a new perspective. A youthful, self-satisfied perspective. For a second or two she felt genuine pride for all her hard work. She just couldn't quite describe the warm and cozy glow she felt from the congratulatory coos. It felt...good.

"Well I think it's bath time for the little ponies," Mrs. Cake then said, “come on, you two.”

With Mrs. Cake's help; Fluttershy changed out of her plastic apron. She couldn't help but notice the mother mare's hoof tapping the underside of her diaper in a less than inconspicuous diaper check. She had to blush for a second as the crinkly fabric momentarily brushed against her crotch, rubbing a cold spot of the diaper against her vulnerable sex. Meanwhile Pinkie effortlessly slipped out of her paint covered outfit, stripping down to just her diaper once again. Fluttershy was quick to notice that Pinkie's diaper was already soaked, stained a light yellow from front to back. That pony had one overactive bladder!

Crinkling their way up to the second floor, the two diapered ponies left the bustling party and joined Mrs. Cake upstairs. It was noticeably quiet up here, now that the three were a fair distance away from the party area. There was a stillness in the air, a far cry from the noisy chatter and commotion coming from downstairs. A central hallway connected a handful of rooms, most of which had their doors closed for the party. The only door that was open, and clearly marked with a florally decorated sign, was the bathroom.

This solemnly used room was lovingly decorated with a womanly touch. A night light with a small colored bulb cloaked the room in a soft lilac light. The overhead lights weren't that overpowering either once they were flipped on and lit up the room with soft dispersed lighting. The room’s color scheme never went with any bright or vibrant colors and instead focused on soft, soothing shades of blues and pinks. It was a room of calm and relaxation. The kind of place one could spend an entire afternoon just soaking in a warm bath with a good book. It resembled a spa more than a bathroom.

Against the farthest wall, past the clean white counter and the child locked toilet was a large tub. This smooth sloped porcelain furnishing was big enough to bathe two ponies at once and probably a common spot for romantic evenings between the Cakes, if Fluttershy had to guess. Probably a lovely place to light some candles and bathe in a sudsy bath mixed with rose petals.

A small plastic basket sat on the floor beside the bath, equipped with a handful of bath toys and scented bubble bath mix. The brightly colored rubber floaties came in adorable and friendly shapes of smooth shaped animals like ducks and elephants and fish. Such a toy collection might have fooled an outside observer into thinking Mr. and Mrs. Cake had children, but Fluttershy knew better than that.

A warm bath was drawn, complete with mint scented bubble bath that filled the room with a soothing scent that steamed away the stress of the day. Mrs. Cake expertly tested the water as it poured into the basin, ensuring that it was just the right temperature before guiding her charges in.

"Alright girls, diapers off and into the tub," Mrs. Cake told the paint covered ponies.

Fluttershy was first, with Mrs. Cake already reaching underneath the yellow pegasus before she had time to react. Her nearly bone dry diaper was quickly undone and slipped off her backside with a faint but audible puff. She felt a little silly letting the diaper go to waste, but surely Mrs. Cake, with her creative and playful mind, had plans for such under used diapers. She was then guided by the hoof into the bath where she found herself slowly immersed in the tepid bath water.

Once Fluttershy was immersed in the soothing, tepid bath water, Mrs. Cake turned her attention to Pinkie, who was not quite as graceful in her pre-bath routine. Before the motherly mare could react, Pinkie leapt into the bath as a pink blur, splashing the other ponies as she dunked her lower half into the sudsy water.

"Oh Pinkie Pie!" Mrs. Cake dotted with a chuckle, shielding herself from a splash of water, “diapers are supposed to come off BEFORE you hop into the bath, you silly girl!”

The motherly mare helped Pinkie climb out of the tub as the pink pony giggled up a storm. She knew exactly what she was doing! She emerged from the bubble topped water bowlegged with the bottom half of her fur already matted and wet. In that brief dunk into the bath water, her diaper swelled up beyond full, coming dangerously close to bursting. The front tapes struggled to keep the whole thing together, weighing down on her waist heavily.

With her diaper dripping a large puddle at her feet, Pinkie tried her best to stand still as Mrs. Cake reached under her huge, saggy diaper. She was giggling so much that she started to wiggle and squirm. Undoing the straining tapes allowed the whole overly inflated diaper to drop to the tiled floor with a heavy and wet plop. For now, the water soaked thing was left where it laid.

"There now let's try this again," Mrs. Cake said, "no more splashing, okay?"

Being on her absolutely, super special BEST behavior this time, Pinkie slipped back into the bathtub with nary a wayward splash out of the tub. With a smile, Mrs. Cake rewarded the pair by adding a number of bath toys into the water, giving the girls something to play with while she scrubbed them clean.

As time went and as Mrs. Cake slowly cleaned the two girls inch by inch, Fluttershy started to play with the toys that floated around her. At first she would simply poke at any plastic boat or squeaky duck that floated by. She would then snatched a floaty or two and pull them under water, giggling to herself as they floated back up to the surface with a little pop. Eventually she found herself playing out little stories in her head about a group of squeaky turtle toys who needed to find a boat to sail across the big frothy seas to return home. Playing these games of pretend were starting to come naturally to her and she found comfort in that.

When the toys were starting to lose their appeal, Fluttershy’s eyes wandered over to Pinkie’s diaper that remained splayed out on the tiled floor a few feet away from them. It was funny to Fluttershy to see Pinkie’s near bursting diaper dwarf her own as the two garments sat side by side. She found a certain kind of fascination with how full those diapers were designed to grow and how much one could hold given the circumstances. Other than the initial accident she had at the beginning of the day, she realized that she hadn’t really internalized the fact that those crinkly things were meant to be used. It was obvious that she’d have to eventually, but to...actually do it? The thought made her cheeks blush.

Before she knew it, bath time was over and Mrs. Cake had two fresh and fluffy towels waiting for the two girls. There was hardly a cold moment between the scented bath waters and the soft wrapping of the light blue towels. As the water drained, Mrs. Cake dried the two ponies off efficiently and quickly.

Suddenly there was a knock at the door, followed by a meek yellow stallion poking his head through the crack in the doorway. “Uhm...mommy?”

"Yes, Carrot, what is it?"

"I-I was just wondering where you were," the stallion replied as he entered the room, bashfully doing his best to avoid looking at the towel wrapped ponies for politeness sake, "you disappeared from downstairs and...I..."

"A sweet boy, but so needy sometimes," Mrs. Cake chuckled to the girls before turning back to Carrot, "well you're just in time, sweet roll. These two were just about to get diapered up after their bath." She continued to fluff the pair’s freshly washed fur, wrapping them up in a bundle of nice warm towels. "I’ll be keeping an eye on Fluttershy tonight, but I believe Pinkie here owes you some playtime?"

"I-I w-would like that very much," Carrot stammered back, his hind legs already shivering.

"Then be a good boy and help me guide these two back to the bedroom so we can get them dressed."

With Carrot’s eager and almost childlike enthusiasm, Pinkie and Fluttershy were guided out of the warmth of the steamy bathroom and made their way towards the master bedroom that waited at the end of the hall.

Pinkie and Carrot walked ahead of the other two with a giddy gait in their step. They nudged and teased each other like a pair of teenagers as their excitement for what was to come started to become palatable. Mrs. Cake was a calm force beside Fluttershy, radiating the confidence of a well experienced caretaker. While Carrot gave off the uncertainty and excitability of an inexperienced teenager, the motherly mare never faltered from her reliable and trusting maternal impression. Fluttershy felt safe around the older mare. Finding her company less of a friendly one and more of a motherly one.

Author's Note

Do any of you read books while taking baths? I'm more of a shower kind of guy so it's never really crossed my mind, but like I've seen people light candles and have trays that hold their paperwork that hang over the tub sometimes, but I've never seen a need for any of that. Maybe I just need to take more bubble baths.

Chapter Seven

The master bedroom, Fluttershy noticed as they entered, had the same sort of feminine touch as the bathroom. The large queen sized bed that hugged the rightmost wall was fitted with matching bedsheets of calming shades of lavender and rose while the wide daybed near the opposite wall was fitted with floral prints and soft pinks. An open case of diapers and a set of changing supplies sat out in the open beside the daybed, seemingly put proudly on display for anypony to see.

"Carrot, would you help mommy and warm up bottles for everypony downstairs?" Mrs. Cake explained, gathering up the diaper changing supplies. "Have Cream Heart help you and bring three up here when you're done."

"Yes, mommy," Carrot nodded before disappearing out into the hallway.

With her diapered husband gone, Mrs. Cake turned to the freshly dried off girls with a smile. "Now then," Mrs. Cake clapped, “who's ready to go first?"

"Not it!" Pinkie exclaimed with a laugh. Of course it was pretty obvious that she was just being difficult for difficulty's sake.

"How about you go first then, Fluttershy," Mrs. Cake then said, "I'm sure Pinkie can behave herself just a little longer."

"No promises," Pinkie giggled.

Fluttershy complied and yet again found herself guided by the hoof to wherever Mrs. Cake took her. The day bed served as a spacious impromptu changing pad for now, something that Fluttershy imagined Mrs. Cake did quite often when the adult foals she watched needed changes. She must have changed diapers on a daily basis, Fluttershy assumed, there always seemed to be some grown pony nearby in dire need of a change. Why Carrot Cake alone must keep her busy on his own with his fussy demeanor.

A new diaper after a warm bath was refreshing to say the least. The crisp padding seemed softer against Fluttershy’s freshly dried fur, smelling just as sweet and clean as she felt. It all made a variety of feelings bubble up inside of her. It was almost paralyzing at times to comprehend the swirl of conflicting emotions she felt as the diaper was wrapped around her. Naughty thoughts fueled by sexual urges mixed with soft thoughts that were coaxed by comfort and littleness. She was happy to feel the snugness and security that came with the diaper, but also felt that tingling sensation in her loins that had been building up all day.

"Back," Carrot announced, waddling into the room with three bottles balanced on a silver tray on his back just as Mrs. Cake was finishing Pinkie's diaper change..

"That's a good boy," Mrs. Cake cooed happily, taking hold of one of the bottles, "did everypony else get fed?"

"U-uhm yeah...M-Ms. Cream Heart even let me practice...holding a bottle for her..." Carrot spoke with a little smile on his face.

"Busy boy," Mrs. Cake replied, "well you've earned your reward. Enjoy your bottle."

With a proud smile growing on his blushing face, Carrot happily carried the remaining pair of bottles to the other side of the room and handed one to Pinkie Pie. Pinkie happily nabbed the bottle and suckled on the rubber nibble as she playfully circled Carrot. She nudged and played with the stallion as she trotted around, bumping her padded rump into his side as she mischievously giggled. Carrot could only think to blush and shyly allow the flirtatious mare to dance circles around him.

Finally Pinkie nuzzled the underside of his diaper, sending a shivering blush across the stallion's face. A raging hard-on immediately grew, bulging out the front of his diaper. Already the poor stallion quivered with weak knees and longing eyes.

Fluttershy continued to stare until she was snapped out of it by the coaxing hooves of Mrs. Cake. With a gentle grip on the diapered pony, the motherly mare helped her onto the ground where she was lowered into Mrs. Cake's lap.

“Shh shh, quiet time, honey bun,” Mrs. Cake cooed as she popped the bottle into Fluttershy's mouth, allowing the pegasus to gently suckle down the sweet, warm milk, “just relax and enjoy your bedtime baba.”

Pinkie Pie and Carrot Cake meanwhile continued to play their naughty games, feeling each other up and sensually kissing each other all over. Pecks on the cheeks were responded with wet smooches on the neck while diaper pats were replied with deep kisses on the mouth and moans. For a long while, the only sounds heard in the peaceful room was quiet moaning, soft crinkling, and Fluttershy’s gentle suckling.

Carrot Cake seemed the most vocal of the group. His squeaky groans of pleasure could be heard more often than not. He lustfully clamored over Pinkie Pie, kissing and twisting around her in sweet embrace. He focused a lot on grinding up against the other pony, pressing his tenting diaper firmly against her as they made out. He was like a horny teen in bed, almost quivering as he moaned.

Suddenly Carrot's murmurs turned into sharp and heavy breaths until finally he let out a whimpering moan. He began to squirm as his waist pathetically twitched up into the air. On his face was a flash of pleasure, followed shortly by bliss, and seconds later regret and worry.

“Tsk, Carrot,” Mrs. Cake scowled, “don’t tell me you finished already!”

“I-I...I...got carried away,” the stallion shamefully answered.

“I would say so,” Mrs. Cake shook her head, “and you didn’t even wait for Pinkie Pie.” The pink pony responded with an exaggerated and playful pout.

Carrot Cake shamefully lowered his head, his body quickly cooling off from the heated orgasm. "I-I'm really really sorry, mommy," he spoke with a little voice, "i-it was an accident..." He truly felt awful for his shameful performance, that was obvious. And that just seemed to make him appear all the more cuter.

Mrs. Cake only scowled at the diapered stallion and tsked with disappointment. “Pinkie," she finally said, "be a dear and grab Carrot's little toy. It's in the usual spot.”

“C-Cup Cake!” Carrot Cake whined.

“Hush,” Mrs. Cake snapped before turning back to Pinkie, “might as well grab the suppositories from the bathroom cabinet while you're at it. If he's going to keep having accidents in front of us, they might as well be entertaining."

“Can do!” Pinkie Pie exclaimed as she hopped to her feet with a happy sprong. “Come on, baby, we’ll get you ready!” With a meek and submissive nod, Carrot Cake followed Pinkie Pie back out into the hall and out of sight.

"Sorry you had to see that, little Shyshy. Carrot's always getting over excited when he's playing with Pinkie," Mrs. Cake explained, "but I'm betting you're loving the show so far."

A blush flushed Fluttershy's face as she couldn't help but nod. Truth be told she was enjoying the show immensely. It was like her own private performance that played out in front of her. Watching Pinkie and Carrot fondle each other like a pair of horny teens was exciting and having Mrs. Cake ordering Carrot around was just icing on the cake.

Carrot Cake returned a few minutes later, trying his best to shrink behind Pinkie Pie who showed him off with pride. He was now sporting a powder blue penis strapped over his diaper. The strap-on was made of a firm material with enough detail in its lifeless imitation that it almost resembled the real thing save for the strange color. The whole apparatus was bound over his diaper with a series of black straps that ensured that the blue penis was properly positioned right over his padded crotch.

“He’s all ready, auntie!” Pinkie so proudly exclaimed, handing off a small white container of suppositories to the other mare.

“Alright, Carrot, bend down for mommy,” Mrs. Cake commanded before she turned her attention to the little filly quietly laying in her lap, "Now Fluttershy, Auntie Cake needs to take care of something real quick. Can you be a good filly and hold onto your bottle until I get back?"

With her cheeks flushed in rosy red, Fluttershy nodded and raised her hooves to take hold of her bottle that still sloshed with a healthy amount of milk. She watched as Carrot crouched in front of her, his crinkly diapered rump raised high up in the air so that his orange tail flagged highly into the sky.

Carrot’s tail tape was undone and the diaper slipped down his legs, exposing his baby powder stained bottom to the open air. Whenever he fussed just a little too much, Mrs. Cake was there with a swift spank on his thigh and a sharp and commanding “hush!”. Fluttershy sucked in an extra large gulp of milk as her cheeks flared up. She couldn't help but picture herself giving Carrot's powdered bottom a firm spanking. Or, for that matter, having HER bottom spanked. What if Big Mac needed to be spanked? Would she pull his diaper down and spank his powered butt too? Was his butt as adorable as Carrots?

As these thoughts rushed through her mind, she watched tentatively as Mrs. Cake popped open the lid of suppositories and rolled one out onto her open hoof. With expert dexterity, she slipped the small blue pill into Carrot's tail hole, causing the stallion to gasp and groan in displeasure.

“Now you give Pinkie Pie all your attention, alright Carrot?” Mrs. Cake said, pulling Carrot Cake’s diaper back into place and taping it snuggly. “It's only fair after you so rudely finished before her.”

“Y-yes mommy,” Carrot answered with a small voice.

Fluttershy watched the whole thing from her spot on the floor, taking in big quaffs of milk as her eyes grew wide. Watching the submissiveness of the stallion made her crotch tingle and hearing Mrs. Cake's commanding tone made the front of her diaper feel muggy. In a feat of mental gymnastics, her deviant mind imagined herself simultaneously taking on the role of the submissive and the dominant. To be in such a commanding and authoritative position. To be commanded to use her diapers whether she wanted to or not. Her mind teemed with sexual thoughts, each one played out slowly so that she could savor every last, breathtaking sensation. And with each arousing thought, came another hungry suckle of milk.

“Take it easy, sweet roll,” Mrs. Cake cooed, taking hold of the bottle once again, ”you’ll get a tummy ache.”

Snapping her charge out of her milk fueled fantasies, the motherly mare snuggled back under Fluttershy, resting the pegasus’s head in her lap once again. Meanwhile Fluttershy so desperately tried to hold back the intrusive thoughts and slow down her suckling, but her face continued to burn warmly and her body continued to tingle all over.

“Wouldn’t want to end up like little Carrot over there, would we?” Mrs. Cake continued as she gave Fluttershy’s soft furred tummy a pat.

Fluttershy felt her face blush and get all tingly again. She looked back at Carrot who already appeared uneasy from the suppository. For a passing moment, her mind fantasized about being in Carrot’s position. She wondered how a messy diaper felt and if she’d even find the courage to do something so demeaning. Would she be able to do it when the time came? Would she have to be forced into it like Carrot Cake? Already filled to the brim with steamy, sexual energy, she tried not to ruin the mood by imagining such things. Instead she watched the erotic scene unfold in front of her.

Carrot Cake laid on his back as Pinkie mounted the diapered stallion with giggling vigor. The light blue strap-on stood firmly upright on top of the stallion's diaper, subtly pressing down on his limp penis that shrunk inside its sticky insides. A deep red blush burned his cheeks as he worried about what was soon to come.

Pinkie meanwhile savored her time on top of Carrot, hardly paying much attention to the stallion's growing discomfort. First she started to rub the front of her diaper against the strap on, allowing the firm dildo to mold its length into the fluffy - and mildly soggy - padding. She thrusted her hips down against Carrot as the dildo was squeezed inbetween the two, all the while moaning loudly and lustfully. Once she was good and warmed up, she opened a leg gatherer of her diaper and guided the dildo into its warm insides.

The direct touch of the dildo against her already moist pussy sent shivers down Pinkie’s spine. Already teeming with excitement and libido, Pinkie quivered and twitched as she resisted every urge against going down slowly. Inch by inch, she lowered herself onto the firm dildo, allowing long and loud moans to ooze out of her drooling mouth. She reveled in the feeling of fullness that the dildo provided, a rare treat she normally never felt when playing with Carrot.

Steadily and rhythmically, she rode the stiff toy while idly nursing her bottle. Between moans and pants, she playfully gummed at her half full bottle, taking in quick squirts of milk to cool her heated body.

Meanwhile Carrot struggled with dealing with the growing pain that was bubbling in his gut. The stallion would wince with every bounce, as the shock rattled the delicate control he tried to hold over the inevitable. Every passing second left his bodily control weaker and weaker and with every bounce he could feel himself closing in on the point of no return.

Finally his eyes shot open wide with desperation. “W-wait...P-Pinkie...” his voice was weak and strained at this point. Sweat beaded down the poor stallion’s face as he struggled to keep it all together. But Pinkie Pie was hearing none of it. Too wrapped up in her feverish bouncing, she was more concerned with her own orgasmic climb to pleasure than the battle Carrot was very quickly losing.

And then, in one pathetic little whimper, Carrot Cake lost all control of his bowels. His hind legs wimply wiggled underneath Pinkie as a liquidy gurgle rumbled his diaper. The runny filth that had been building up in his gut finally dropped into the waiting diaper, bellowing out the pristinely white padding and staining it with an embarrassing hue of brown. Weak, hasty grunts pushed the rest of the mess into the diaper, only to immediately get pressed under his weight as Pinkie continued to bounce on top of him. Once he started, he could do nothing but allow the rest of his humiliation pass as his diaper grew heavier and heavier underneath.

Carrot was left shamefully exhausted, his body tired from holding back the painful swell in his belly only to have it all lost in an instant. He grew quiet, too embarrassed to even look his mommy in the eye during these trying times. The subtle squishing sounds, not to mention the very childish scents that seeped out of his diaper kept him still. The only thing he could do was quietly suckle on his milk bottle and wait for Pinkie to have her fill.

Pinkie meanwhile didn’t lose a beat, not even slowing down as Carrot made a mess of things. She might not have even noticed him filling his diaper deep in the throes of her sexual bouncing. She continued to moan and pant loudly, enjoying every inch of the powder blue dildo as it slid in and out of her slick pussy.

Fluttershy stifled a gasp as she watched the whole thing with wide eyes. The desperate struggle for control, the weak pleas for mercy, and even the subtle bulging that ballooned out Carrot’s diaper. It was just like when she watched Big Macintosh soil himself earlier, a memory she fondly recalled. Only now she was keen enough to pay attention to every minute detail that unfolded in front of her. She felt the same tingly, blush filled response bubbling inside her as well. Not to mention that familiar hot and humid feeling in her diaper. were all details the meek pegasus focused heavily on.

She didn’t quite know how long she stared at the sight, but after a while she was snapped out of her staring contest with Carrot's bulging, brown diaper when an invasive hoof pressed into her warm padded crotch.

“Enjoying the show, little Fluttershy?” Mrs. Cake whispered as she kept up the rhythm, rubbing deep and sensual circles into her diaper.

The motherly mare dug deeper into Fluttershy’s warm diapered crotch, driving the young pony crazy. The milk bottle did only so much to muffle the long, drawn out moans that squeaked out of the pony's mouth. She very quickly became quivering puddy in the mother mare’s hooves and could feel her inhibition slip. As Pinkie continued to bounce on Carrot’s tireless dildo, Mrs. Cake picked up the pace and rubbed fast and deeper into Fluttershy’s moist sex.

"Such a vocal little pony," Mrs. Cake chuckled, "crinkling and squirming up a storm in her little diapers. I bet my little Shyshy would just love to join in, huh?”

The sex crazed side of Fluttershy wanted to scream out a desperate “yes!” But whatever fragments of self control she could conjure up kept her bottle pressed firmly against her muzzle, plugging up any embarrassing pleas that came dangerously close to slipping out.

“I bet if you asked extra super nicely, those two would let you get all stinky and sticky with them,” Mrs. Cake continued to whisper, “what are friends for after all.”

She was too embarrassed to admit it, but Fluttershy now knew how lewdish and perverted her thoughts had become! She wanted to wear diapers and wet them and waddle around in them and have sex with a hot stallion in a diaper! Yes! And be forced to fill her diaper completely and be humiliated in front of all her friends and be told she’s nothing but a baby who can’t have sex outside her diapers! She wanted to wear diapers forever! Yes, she wanted all that! She wanted that!

To put the final cherry on top, Mrs. Cake leaned in close, whispering with a sweet, sensual voice into Fluttershy’s blush filled ear, “betting Little Macky would enjoy himself too.”

With a shocked gasp, Fluttershy was sent over the edge. Her eyes shot open and her thighs squeezed together tightly as a climactic sensation sent her whole body into twitchy convulses. Any moans or panting the yellow pony could manage to make during her throes of pleasure was overpowered by Pinkie Pie's moans as she continued to ride Carrot’s strap-on with unrelenting energy and vigor.

Fluttershy squeaked and whined as her legs compulsively wiggled and squirmed. She might very well have slid out of Mrs. Cake’s hold if the older mare wasn’t holding her steady with her hoof still wedged between Fluttershy’s thighs.

"Oooh dear," Mrs. Cake's voice teased and taunted the exhausted pony, "I bet that felt really good, huh? And with that big diaper on there isn't even a mess to clean up. Lucky you!"

The praise left a genuine smile on Fluttershy's face as she rode out the blissful climax that felt as if it had been building up all day. Safely nestled in Mrs. Cake’s lap, the diapered pegasus squirmed and weakly kicked as she reveled in the afterglow. Her thoughts returned to normal as the burning sexual urges subsided for now. She felt so content in the motherly mare's arms. She felt like she could just suck on her hoof and fall asleep right there.

"I'll be back in a moment, you two," Mrs. Cake called out to the other ponies, her words only barely audible to Fluttershy, "I think it's naptime for good little ponies." Delicately, she pulled her charge off the ground, plucking the empty bottle out of the peagsus's mouth before helping her out of the room.

Fluttershy was floating. Still dazed from her bliss filled climax, she struggled to walk straight. The short walk down the hall proved to be quite the challenge for the dazed pegasus. It took Mrs. Cake's guiding hoof to keep the dazed pony from tripping over her own sluggish feet.

Eventually the pair entered a room that appeared to be a nursery, only better equipped to accommodate older ponies. The whole room was cloaked in a starry nightlight that casted twinkling stars on all the walls that slowly rotated around the room. Two large cribs sat across from each other on the far end of the room, each one with clean bed sheets neatly made inside.

The cribs looked like a cozy spot to spend the night in. A cozy spot to end a cozy and exciting day of new experiences. It had been a big day of learning new things about herself and having fun, especially with Macintosh. Macintosh!

"W-wait! Where's Big Mac?" Fluttershy suddenly exclaimed.

"Missing your little friend, huh?" Mrs. Cake replied, "don't worry, he'll be in soon. Getting close to his bedtime too." She tucked the yellow pegasus in tightly, wrapping her up in a nice warm blanket. “He’ll be sharing your crib for the night. Pinkie gets her own crib since she tends to leak. Even through her double night time diapers!” Mrs. Cake chuckled, "you don't have to stay up for him, don't worry. You had a big day today."

"I...had a lot of fun playing with him today," Fluttershy admitted.

"I know you did, sweetie. He really likes you, I can tell," Mrs. Cake winked.

"Will he...have time tomorrow to play?"

"Of course, sweet roll, tomorrow's a whole new day," Mrs. Cake said, giving Fluttershy's forehead a sweet and delicate kiss, “good night, my little diaper butt.”

Tucking the little, yellow pegasus in for the night, Mrs. Cake tip toed out of the room. The faint blue glow of the nightlight kept the room cloaked in twilight as Fluttershy snuggled into her bed for the night.

Cuddling up in her mound of soft blankets, she let out a big breathy sigh. What a day. What an exciting and eventful day! In all her life she never imagined herself in such a situation. To tote around in diapers. To play with foal toys. To be treated like a little filly. She never thought she'd ever feel so vulnerable, so pleasant and tingly, or...turned on. It almost all felt like a dream if it wasn't for the sticky warm spot that hovered around the crotch of her diaper.

And tomorrow was a new day indeed! She couldn't imagine what she'd get herself into after a refreshing nap. She really wanted to stay up to see Big Macintosh come to bed. She couldn't exactly explain why or what she'd even do when he got here. Maybe they'd cuddle? Or...did she just want someone else in her crib to keep her company? She wasn't really sure. And quite frankly she was too tired to think.

Another yawn interrupted her train of thought, reminding her just how tired she was. Sleep was the more important thing right now. Sleep and then tomorrow was a whole new day.

Chapter Eight

That night, Fluttershy's dreams were made of sunshine. Or at least it certainly felt that way to the flutter hearted pony. All throughout the night she dreamed of soft and comforting things that made her heart glow with a warmth that she hadn’t realized she had been longing for her whole life. If she had to guess, it was because of the comforting environment she knew she was laying in in the waking world. She knew that she was safe there so she was safe to dream these soft and delicate dreams.

She dreamed about a lot of things, but each time the scene changed or whichever direction the little stories would go, it always transitioned calmly and seamlessly. One moment she floated through the halls of a pastel colored castle made of sparkling pink and green and blue clouds. In another she'd be walking through open fields of twinkling golden grain. But she was never frightened by the change. She never felt scared or afraid. She was safe and warm.

When morning finally came, a lingering, fuzzy sensation glowed inside her chest. Still bundled up in the warm cluster of blankets, Fluttershy was almost too comfortable to move. She took several moments to finally stir from her restful slumber, only opening her eyes long after she became aware of her waking body. The smell of floral fragrance and baby powder welcomed her as she ever so slowly opened her eyes to the blue morning sun.

The sunlight lit up the room around her, allowing her to fully take in her surroundings. The walls were painted a calming dark blue which only made the room feel softer. A soft yellow dresser could be seen not too far away from where she laid as well as a bookshelf and box of toys. What caught her eye the most was the large changing table that hugged the leftmost wall, a sight she almost couldn’t believe. It was a full blown changing table with diapers and everything! Without even realizing it, she had spent the night in an actual nursery! It was almost enough to make her breath quiver like last night.

As she looked around her immediate surroundings, she was quick to notice none other than Big Mcintosh sleeping soundly beside her. His large, muscular frame lit up in the morning light, allowing Fluttershy to see every gentle breath the slumbering stallion took. He looked like a big red teddy bear sleeping so soundly. She thought she could easily spend the entire morning snuggling up with such a huggable plushie.

The sunlight also illuminated Mcintosh’s diaper which she paid extra close attention to. In a way, the extra fluffy bulk around the stallion’s waist made him look cuter and...hotter. It appeared dry, disappointingly so. For a fleeting moment, Fluttershy fantasized about Mcintosh being a bedwetter and waking up every morning in soaked padding. She imagined the big stallion waking up with a whimper, crying for his mommy as his diapers drooped all the way to his knees from a night time’s worth of accidents. It was enough to make her sigh longingly.

It took every ounce of rational thought for her not to start poking and rubbing Big Mac’s thickly diapered rump. Her morning arousal screamed at her and begged for even a little touch, but her natural shyness and meekness kept her from getting carried away. Because what if he woke up? What if she was breaking some unwritten rule? What if Mcintosh told Mrs. Cake about it and Mrs. Cake had Fluttershy kicked out onto the streets?! No, for now, Fluttershy had to stick to her wits.

Minutes later, Mcintosh began to stir. Fluttershy immediately snapped her limbs close to her body in a rigid attempt to appear as natural of a sleeping position as possible. The stallion groaned as he rolled onto his back, stretching every limb high up into the air as he let out this cutest little squeak before letting them drop back down to his sides. He rubbed his face, squeezed his eyes, and finally squinted at the morning sun with a yawn.

Fluttershy dared not move a muscle. As Mcintosh shifted and stretched, she remained rigid and on her back, staring up at the ceiling trying to figure out when was the best time to let him know she was awake as well. Even as he started to move about in his half of the crib, she tried her best to remain still. It wasn’t until Mcintosh decided to take this moment to adjust the front of his diaper uncomfortably that he finally noticed Fluttershy beside him.

"G-g'mornin'," the big stallion so bashfully said.

"Good morning," Fluttershy replied.

"Uhm...how d’ya sleep?"

"I...actually slept really well," Fluttershy replied, yawning cutely as she rubbed a tired eye.

"Good, uh...me too," Big Mac answered, "slept like a baby." He nervously chuckled.

"Heh, y-yeah..."

There was a long moment of silence as the two bashful ponies timidly avoided making eye contact. Eventually Big Mac broke the stillness by reaching out through the crib bars and grabbing something shiny from the nearby dresser.

“Listen uhm," he started to say, "M-Mrs. Cake wanted you ta have this.” He handed off a small metal key dangling on a red ribbon, “it’s the key to uhm...mah cage...”

"Oh," Fluttershy replied, accepting the gift with a unique mixture of shock, second hand embarrassment, excitement, and playful lust. She thoughtfully dwelled, if only for a moment, on the importance of being somepony's keyholder. She recognized how much of a big responsibility this was. To hold onto such a little item meant so much to those who put so much trust in one another. It was thrilling!...It was nerve wracking. It made her eager to fill the day with as many games as possible!

"So i-if ya ev’r think that ah uhm...earned it," Big Mac so bashfully explained, avoiding any direct references to his chastity, "Ah'd ‘preciate being unlocked..."

"Oh..."

"B-but a-ah'm not askin’ you now!" he quickly stammered out. "'Uhm...good colts don't ask to be unlocked,'" he parroted a well rehearsed rule that Mrs. Cake must have gone through great lengths to teach him.

Fluttershy let out an involuntary "aww," before she caught herself and stammered something else, "u-uhm, well thank you for...this. I-I’ll keep it safe, don't worry." For safekeeping, Fluttershy tied the long ribbon around her neck so that the key hung like a necklace. This way she wouldn't lose it and, more deviously, it helped Mcintosh remember what power the yellow pegasus had over him.

"Good morning, sweet rolls," Mrs. Cake entered the room with a singy sing voice.

Pinkie bounced excitedly in the other crib, peeking over the bars with a giddy smile. “Good morning Mrs. Cake!” she cheered. Even in the morning, the pink pony had this spry energy in her with hardly an ounce of the morning sluggishness the other two diaper ponies had. It was tough to figure out whether she had just woken up or she had been up this whole time.

Mrs. Cake tended to the chipper pink pony first and lowered the crib’s side to let her out. “Another wet night by the looks of things,” the motherly mare tsked, “just look at that soggy little thing!” Pinkie only playfully giggled as Mrs. Cake called attention to her double diaper that had swollen to a dangerously full state. The whole thing had darkened a deep yellow hue from front to back. It looked like the smallest bit of added wetting would cause the whole thing to burst.

After carefully helping the diapered pony out of the crib, the pair moved over to the changing table. Pinkie had a sort of excitable giddiness to her stride as she waddled her way across the room. She practically bounced her way there, making her heavy diaper slosh noisily in the quiet room. It was a risky game, moving around so much with such a full diaper, but it seemed as if Pinkie enjoyed the riskiness of it all. Fortunately, or supposedly unfortunately in Pinkie’s eyes, Mrs. Cake helped the giddy pony onto the changing table without a single dribble of urine escaping the diaper.

Pinkie Pie looked ecstatic to be laying on the changing table. Fluttershy imagined being changed on the table was a world of difference from a padded mat on the floor. She hoped that she'd have the privilege of being changed there as well in the near future. It couldn't be right now though, since her diaper was currently completely dry and she didn't have the courage to wet herself in front of Mcintosh, but definitely the near future.

"Good morning, you two," Mrs. Cake appeared beside Fluttershy, snapping her out of her thoughtful daze.

"'Mornin’," Mcintosh said with a shy smile.

"G-good morning, Mrs. Cake," Fluttershy added between yawns. She still needed a bit of time before she was fully awake.

“Do you two need a change as well?”

“N-no, M-Mrs. Cake,” Mcintosh stammered, shrinking back with a blush.

“Hmm, I’m still going to have to check your diaper,” Mrs. Cake answered as she lowered the crib's side, “JUST to be sure.”

Despite his meekness, Mcintosh didn't put up any kind of fight as Mrs. Cake reached in to check his diaper. He fussed and fidgeted quietly, but Fluttershy was starting to realize it was all part of the act. He reveled in the fidgety toddler routine and Mrs. Cake was more than happy to oblige. Although his bashfulness around Fluttershy seemed genuine. Like wearing and wetting a diaper in front of her was so much more of a challenge for the stallion.

With his back legs splayed out wide, Mcintosh's pillowy crotch was completely exposed and susceptible to Mrs. Cake's very thorough diaper check. She poked and prodded every inch of his diaper, tugged at it's waistline for snugness and even gave the back a quick pat. The whole routine confirmed that he indeed didn’t need a change.

With a nod of approval, Mrs. Cake's inspection moved seamlessly over to Fluttershy. “And Fluttershy! My, you’re almost as dry as Little Macky here!” Mrs. Cake said as her hoof gave the yellow pony’s diaper front a little poke, “we might have you potty trained soon!”

It was all role play talk to them, but Fluttershy couldn’t help but feel a quiver of giddiness at the thought of potty training play. Rushing to the potty and being praised every time she made it. Gentle assurance when she didn’t. Potty training charts hung on the wall as a constant reminder of her past successes and failures. She was only just getting used to the whole diaper thing and already she could feel her mind fantasizing about this new thing. Another time, she told herself, another time in the near future she hoped.

“Okay, you’re all set. Off to the kitchen, sweet rolls! Off you go!” Mrs. Cake chirped. And with a chorus of crinkles, the group waddled out the door.

The kitchen area on the ground floor had just about returned to its former glory with a majority of the baby stuff put away for another day. Toys were packed away in boxes, painting supplies were cleaned up, and the large banner that greeted Fluttershy at the beginning of it all was rolled up and tucked away in a pile. The only remnant of yesterday's party that Fluttershy could spot was the row of large highchairs sitting against the far wall.

"Gooooood morning, little ponies!" Cream Heart sang from across the room.

The mare was already by the stove, cooking up a storm. The smell of rich buttermilk pancakes and vanilla filled the room. She wore a pink apron around her waist, stained with wayward spots of pancake batter, flour, and what appeared to be brightly colored baby food. Carrot Cake was standing beside her acting as her assistant as she prepared enough food for everypony..

"I'm afraid a lot of the little ones had to go home after having an early breakfast,” Cream Heart added as the group filed into the room, “but that's okay. It just means I have more time to keep an eye on you troublemakers!"

“Well come on, little ones! Into your chairs!” Mrs. Cake chirped as she ushered the group toward the row of highchairs.

"Ou! I'm starving!" Pinkie Pie exclaimed with a happy sproing and was the first one to be seated. The rest of the diapered ponies, including Carrot Cake, were seated and locked into place shortly after, but didn't nearly do it with as much energy. It seemed like Pinkie was the only real morning pony among the group.

In no time at all, plates of fluffy pancakes were passed out and placed on each of the ponies’ feeding trays. Alongside every plate sat a bulky spoon made of a bright colored plastic. Each stack was given a healthy amount of butter on top as well as a generous helping of syrup. The sight of the lovingly made meal made Fluttershy's mouth water.

Mrs. Cake pushed a chair within a hoof’s reach of Big Mcintosh and Carrot Cake and made herself comfortable between the two diapered stallions. She grabbed Mcintosh’s spoon off his tray first, but from where Fluttershy sat, she could hardly see everything that was going on over there.

"B-but ah dun want any special medicine," Mcintosh could be heard whining.

"That's all you're having for breakfast today, Little Macky," Mrs. Cake replied, already scooping up a bite of pancake with the spoon, “be a good boy and eat your food.”

“Special medicine?” Fluttershy asked, her ears perked with curiosity.

“No need to worry your little head about that, Little Shyshy,” Cream Heart chimed in, scooting her seat close to Fluttershy’s highchair, “you’ll be getting some as well!”

Mrs. Cake handed off a plain looking plastic container to Cream Cake and she began to unscrew the lid. The container was no bigger than a pill bottle and contained a small amount of a fine pink powder. She sprinkled the powder onto the top of Fluttershy’s buttery pancakes which quickly dissolved and blended into the syrup.

After a few seconds Cream Heart cut off a chunk of pancake with the spoon. “Open up for me, Shyshy,” Cream Heart cooed, “don’t worry. The medicine isn’t harmful.”

Fluttershy hesitated for a moment, but very quickly warmed up to Cream Heart’s trustful smile. She tentatively opened her mouth and allowed the older mare to feed her the sticky, syrup covered pancake chunk. The pancake had such flavor to it that any reservations she had about the meal quickly evaporated once the other mare had another bite ready for her. It was so delicious!

If she tried chewing very carefully, she could almost taste what she assumed was the added flavor of the medicine powder. The powder faintly tasted like orange juice, but was dull in it’s flavor. The sugary sweetness of the fresh maple syrup almost completely overpowered the medicine’s taste and one would have to really pay attention in order to even notice.

Fluttershy pondered on the strange tasting powder as Cream Heart methodically fed her her pancakes spoonful by spoonful. She wondered what the medicine actually was and why Big Mcintosh was whining about it. Was it a sleep aid? Some kind of painkiller? A special blend to make her mouth numb so she’d be unable to talk and end up drooling like an infant? Her mind conjured up a dozen and half possibilities. Or maybe it was just vitamins and she was over thinking. A healthy precaution Mrs. Cake was taking to make sure the ponies in her care were well fed. But then again...Pinkie Pie and Carrot Cake wasn’t given any...

“I like your little necklace, Fluttershy,” Cream Heart said as she scooped up another bite of pancake.

“I-it was a...present,” Fluttershy meekly answered.

“Well I’ve changed enough diapers to know what lock that key goes to,” the older mare chuckled, “I hope you plan on making him really earn it before you do.”

“E-earn it?”

“Of course, stallions will do just about anything if it means they get their cages off. The longer they wait, the more desperate they get,” Cream Heart then lowered her voice, “and between you and me, sweetie, Little Mcintosh over there has been waiting quite a long time already for his cage to be unlocked.”

“H-he has?”

“Should have seen him last night,” Cream Heart answered, “the naughty diaper butt was fussing and whining and grinding against just about any plushie he could get his hooves on.”

“O-oh,” Fluttershy shrunk back a tiny bit in her seat as she blushed. She figured while she was having fun in the Cakes’ bedroom, Cream Heart must have been tending to the other ponies downstairs, most likely teasing Mcintosh like crazy. She sort of wished that she could have been a fly on the wall for that night. Being able to see what silly games the other diaper ponies got themselves into while she was watching Pinkie and Carrot go at it.

“So I really do hope you make him really earn it,” Cream Heart added, scooping up a fresh pancake chunk, “you’ll think of something, I’m sure. It'll be more fun for the both of you,” Cream Heart winked.

Fluttershy gulped heavily at the idea, but couldn't help giving it some thought. If she played her cards right she could very well have Mcintosh wrapped around her hoof. She could make him do just about anything for her! She could have him crawling around and sucking his hoof. She could even have him groveling like Carrot Cake. Her tummy tingled at the vast amount of possibilities.

Breakfast finished soon after that, with the rest of the meal going on uneventfully. When everypony had their fill, Pinkie, Fluttershy, and Mcintosh were guided into the living where yesterday’s party’s diaper changing station was replaced with a large playpen.

The playpen was a temporary addition to the living space and was large enough to comfortably fit six ponies if there was ever a need for that. The walls were lined with a fabric mesh, just thick enough to keep wandering ponies inside the pen. The floor was lined with a thick, colorful play mat that stood firm underneath a pony’s weight, but still had a little bounce and cushion to it.

"Now play nicely, you three," Mrs. Cake cooed as she handed off a trio of freshly warmed milk bottled, "Cream Heart, Carrot, and I have some cleaning to do around the house. We're a short call away if you need anything!"

And with that, the three diapered ponies were left with their bottles. Pinkie was the first to lose interest in her drink. The toys scattered around the pen seemed much more entertaining than a boring ol' bottle of milk.

Meanwhile Fluttershy quickly suckled on her bottle's nipple. The sugary breakfast had worked up quite a thirst. Although the more she drank, the more she knew she'd have to pee. Especially with her bladder already full from last night. But that thought didn't concern her. A wet diaper wasn't that bad. What did concern her was the loud gurgling starting to emanate from her gut.

“It’s the medicine,” Mcintosh appeared beside her with an understanding look, “the medicine is supposed ta help us...y-you know...go...”

Fluttershy now paid closer attention to her rumbling belly. “I-I wasn’t having any trouble going before,” Fluttershy reasoned, "wh-why would they give that stuff to us?!"

The stallion grew quiet and his face flared up a bright red. "...B-because ah asked them to..." Mcintosh admitted, "b-but a-ah didn't know she'd do it ta you too! Honest!"

Fluttershy peered downward toward her belly that was starting to growl and gurgle more intensely. "H-how long is it going to take?"

"N-not long," Mcintosh replied, “u-uhm...m-my advice...t-try to distract yourself and uhm...just relax...”

Trying her best to take to the recommendation, Fluttershy waddled over to Pinkie Pie who had amassed the majority of the pen toys into an easy to reach pile. The pink pony was more than ecstatic when the other two joined her and happily shared her scavenged spoils. She was more than willing to share her supply of plushies, plastic blocks, and sensory toys.

The toys served as a minor distraction to the impending embarrassment she could feel looming overhead. She tried her best to ignore it all, but there was always that little voice in the back of her head asking “what if?” What if she couldn’t do it? What if her diaper leaked? What if the other two no longer wanted to be her friend after she did do it? What if she couldn’t look her friends in the eye again after she did? It was a thousand questions in her head, every one of them unanswerable until the medicine finally worked it’s magic.

Her bowels quickly grew full and heavy as the minutes ticked by. It wasn't a sickly sensation growing in her gut, but a weighty pressure. No matter how much she tried to distract herself with the colorful toys, her gut would constantly gurgle and groan as if it was begging for attention.

Meanwhile Mcintosh was battling some growing pressures of his own. On one hoof he knew from experience that trying to hold it in would be impossible. He knew eventually he would have to go. But on the other hoof, even Fluttershy could detect an obvious bashfulness on the stallion’s face. He was too shy to do it in front of her.

With all that considered, it was Mcintosh that submitted to the urge first.

A long drawn out groan signaled the stallion's demise as he hunched forward. Toys were abandoned as his head dropped to the ground and his soggy diapered butt rose high into the air. Slamming his eyes shut, he began to grunt. His diaper inflated in the back as a large messy mass was pushed into it.

Fluttershy had very little time to watch. Despite having an ever mounting interest in watching the grown stallion use his diapers, her bowels could no longer hold back the inevitable. Wincing in pain, she hopped up to her feet and in seconds her tail was raised up into the air and she began to squat as well.

With only a little bit of pushing, the mass that built up in her bowels slipped out painlessly and smoothly, filling up her pristinely white diaper. On top of that, her bladder took the opportunity to relax as well and sprayed into the stinky interior of the diaper even as it continued to sag lower with more mush. Before too long, her gut and bladder could finally relax and she was left with a rather weighty and warm diaper hanging off her hips.

She didn’t dare look up from her humiliating position. Her face burned a hot blush as she hid behind her forehooves. Her mind filled with conflicting reactions to the infantile deed, each one more powerful than the last. It was a gross feeling, demeaning, and oddly enough...strangely erotic. Her meek body struggled to make sense of it all. It was humiliating to soil herself in front of others. It was shameful to allow herself to have an accident like a foal. But at the same time...it was incredibly, undeniably arousing!

"Eeew!" Pinkie could be heard giggling, "Mrs. Cake! Mrs. Cake! The babies had an accident! The babies had an accident!"

Minutes later, Mrs. Cake came into the room with a casual trot. “What’s that, Pinkie?” she asked so nonchalantly.

“Fluttershy and Little Macky pooped their diapers!” Pinkie Pie answered with glee as she pointed at the blushing pair. She seamlessly took on the role of an older sister, hellbent to tattle on others.

Mrs. Cake looked over at the other two ponies. Both blushing furiously and shamefully hiding messy diapers behind their tails, Fluttershy and Mcintosh were practically twins from their embarrassed disposition down to their very wet and very full diapers.

"Phew! Looks like I got a pair of stinky diaper butts!" Mrs. Cake theatrically exclaimed, covering her nose with a hoof for added flair, "come on, you two, let's get you changed!"

Carefully and with meticulous hooves, Mrs. Cake helped both ponies out of the playpen one after the other. She paid close attention to the pair’s messy diapers which remained unsquished and untampered with. Less of a mess for her to clean up, Fluttershy assumed. She then guided the two ponies back upstairs where they returned once again to the nursery.

Fluttershy was the first one to be changed and, as careful as before, was helped onto the table with no time spent idling. Being changed on the table really was something else. Having a firm, supportive pad under her made her feel safer in a funny way. Stranger yet, it made her feel smaller. She kinda felt like idly kicking at the air above her or carelessly drooling on her face. There was something magical about the changing table, something that made her want to act even more like a foal.

Next time, she promised herself, next time.

“There’s the little flower butt I remember!” Mrs. Cake finally said, “nice and clean!”

“I-it’s over already?” Fluttershy exclaimed with a squeak, sitting up to find a fresh diaper now taped around her waist. Remnants of baby powder could still be smelt in the air as the crisp, new diaper crinkled loudly with every slight move she made. She had almost forgotten how good a clean diaper felt.

Mrs. Cake just chuckled as she helped the sweet smelling pegasus off the table, “I guess somepony likes getting their diapees changed! But you’re not the only one in dire need of a changie today.”

Fluttershy glanced over at Big Mac who was still waiting patiently by the table. His diaper still sagged well below his tail, in desperate need of a diaper change very very soon. She could keep him in that diaper for a little bit, Fluttershy figured. If she only asked, she was sure Mrs. Cake would forego the needed diaper change just for a little bit. All she had to do was ask! The idea made her gulp. All she had to do was ask...

“Alright, poopy butt!” Mrs. Cake said to Big Mcintosh as she moved back to the changing table. The stallion laid patiently on the table, his swollen diaper bulging out his waist. ”Your turn!”

Fluttershy’s heart began to race. If she was going to do it, she had to do it now!

Author's Note

This chapter reminded me of this one time I was given a diaper change on an adult size changing table in a hotel room. It was during a furry convention and I was hanging out with friends, floating from one hotel room to the next which eventually led us to chilling in a room where someone had brought a big, heavy changing table with optional leg and arm straps. I didn't even know the name of the guy who changed me on that table, but it was sure one heck of an experience! After being changed on beds and floors, having a sturdy, properly leveled table where your legs didn’t hang off the side to be changed on made an incredible difference!

Anyway, don't know if that story should have a life lesson attached to it or not (maybe like "always know the name of the person who’s changing your diaper so you can thank them properly"?), but hope the chapter was worth the wait!

Chapter Nine

“U-uhm Mrs. Cake?!” Fluttershy practically yelled out with a forehoof flung out before her. Only a mere second later she immediately pulled it all back, “c-could you maybe...uhm...NOT change Mcintosh’s diaper?”

“Oh?" Mrs. Cake answered, her hooves hovering inches away from the straining tapes of Big Mac's diaper. "Whatever for?”

Fluttershy nervously fidgeted with the key around her neck, “I-I uhm...w-want him to uh...earn it...Please?”

Mrs. Cake paused for just a moment, but as all of it clicked into place, the older mare smiled impishly. “Oh is that so?” she finally said with a grin as her hooves pulled away from Mcintosh’s diaper, “alright, sweetie, just because you asked nicely.”

“What?!” Mcintosh exclaimed with a groan, “b-but M-Mrs. Cake!” His voice rose into a squeaky whine. A most unexpected tone from such a mature looking stallion.

“Don’t fuss, Little Mack! You KNOW very well the responsibility you entrusted Fluttershy with when you gave her that key,” Mrs. Cake chided, “she calls the shots and she asked that your diaper not be changed.”

“B-but it’s so...” Mcintosh’s voice got smaller and as the authority of his words got weaker, “so...full...” He said those last words with such a tiny voice that it was barely audible.

“I’ll give you two some alone time then,” Mrs. Cake said, packing up the changing supplies, “call me if you need anything, alright Fluttershy?”

“Th-thank you, Mrs. Cake,” Fluttershy replied with a furious blush warming her cheeks.

And just like that, the two diapered ponies were left alone in the nursery. Fluttershy with her freshly powdered behind enjoying the softness of a new, crisp diaper. And Mcintosh who pulled himself off the table with a defeated slump, his brown stained diaper bulging and sagging out the back. He looked cute in such a state. Almost like a pouty toddler being told to put away their toys for the day.

Fluttershy felt a quiver of excitement swell inside of her as she watched the stallion. But at the same time, a pang of worry stirred in her chest. “I-I’m really sorry for that,” she immediately began to backtrack, feeling an itch of guilt about the whole thing, “i-if it’s really a big problem for you, I-I can-”

“No,” Mcintosh interjected, “you have the key. You call th’ shots.” He then looked up to Fluttershy and for a few short seconds, their eyes locked and sparks danced in the air between them. “Ah want this. A-ah want you to keep going...”

The spark turned into heat as the two ponies’ faces flared up with an aroused blush. Their breaths became erratic and shaky and their heartbeats quickened. Keep going, their eyes said.

"O-okay," Fluttershy managed to stammer out.

So this was it. She had him where she wanted him. Now what? Before now she could think of a dozen and a half scenarios that she wanted to play out with Mcintosh. All that time she spent daydreaming and lusting over the stallion from a distance gave her mind ample opportunity to conjure up lewdish and silly ideas that she only dreamed could come true.

But now she was here. She got what she wanted. A needy diapered stallion who was into all of it as much as she was. Now that the opportunity finally struck, her mind was paralyzed with choice. What if he didn’t actually like the stuff she did to him? Did that matter? What if he got too upset or angry? Did THAT matter?

Leap of faith, Fluttershy. Leap of faith.

"A-alright well first...I uhm, n-need to give your diaper a proper check," she finally said, starting with something so seemingly small. It almost felt like a trifle thing to ask for and yet her cheeks burned with a bright pink. She spun her hoof in the air for added flair, "t-turn around...please...honey." The cute little nickname at the end made her tongue tingle.

Being a good little colt, Big Mcintosh turned on his heels, spinning his thickly diapered butt closer to Fluttershy. A strong whiff of baby powder and earthy filth flew past her face before the stallion’s diaper landed firm, inches away from her muzzle. The concoction of scents called attention to itself almost as much as the deep shade of brown that now wrapped around the better part of Big Mac’s backside did. Musty urine mixed with sleepy lavender mixed with sweetly sour stink.

And despite all that, Fluttershy didn't feel the revulsion she assumed she was expected to feel. The mixture of smells didn’t make her sick or make it hard to breathe. It wasn’t a bad smell, not entirely. It was kind of a cute stink. An adorably stinky diaper wrapped around a stud of a stallion.

After a few moments of stillness, the yellow pegasus leaned in and dared to touch the soiled thing. It started with a tiny, tentative pat which was followed up by a very light press. Then after that, she allowed her hoof to rest on the bloated backside of the stallion's diaper. The diaper was squishy and pleasantly warm. It was like resting her hoof on top of a smelly, plastic covered electric blanket. The warmth. The crinkling. The way it molded and moved around like smooth clay. It felt soft. It felt disgusting. It was a feeling that she couldn’t get enough of! It made her chest feel silly. It made her nose curl in distaste. It made her feel tingly and aroused.

It was then she felt brave enough to experiment with a swift smack, causing Mcintosh to quietly yelp with surprise. It was a light smack, barely making any impact or even an imprint in the yellowish brown material that ballooned behind him. And for a brief instant, Fluttershy gave pause. The single spank made her hoof tingle and her heart quiver. She looked at the hoof with newfound excitement that was bubbling to the surface as a tiny smile.

So shortly after the first pat-spank, Fluttershy dared another, soliciting a similar response from Mcintosh. She then dared another, smacking harder and pressing deeper into the pillowy, plastic material. Then another and then another.

It was tough to say what her end goal was with those pat-spanks. It wasn’t to punish the stallion for doing exactly what he was told. It wasn’t to shame him by reminding him of the mess he made. It wasn’t malicious or painful. It was just...she couldn't quite explain it. She just couldn’t quite get enough of the pressed pat-spanking. It was arousing in a way. Empowering in another way.

She imagined this was how Mrs. Cake felt when she was doling out punishments for misbehaving foals. Roles of power often mixed in the real world, but there was a finer definition in situations like this. Those in charge spanked, those who followed got spanked. If she wasn’t such a nervous little filly she imagined she’d enjoy the role of spanker quite a lot.

"Naughty diaper colts deserve spankings over mommy's knee," she imagined she'd say, pulling Mcintosh away from whatever he was doing to give him a spanking.

It wouldn't matter if he was dry or messy or wearing a diaper at all, if the mood struck her, Fluttershy imagined herself pulling the stallion over her lap to give him a firm spanking. And Mcintosh would cry and cry and cry. Writhing under his mommy's hold, squirming feebly in her lap. He'd fuss, but dare not wiggle his bottom out of the way.

In reality though, the stallion just stood there quietly with his head low to the ground. He nibbled on his lower lip to muffle hushed moans that slipped through his muzzle with each squishy smack. Not crying or whimpering like Fluttershy had kinda sorta hoped. Just privately bracing himself for each soft sequential spank that squished his shameful stink oh so subtly against his sensitive backside.

After all of Fluttershy's daydreaming, she realized she was starting to leave quite the depression in Mcintosh's diaper. The lumpy mush had become flattened after her ten or twenty or fifty-some-odd pat-spanks.

"S-such a...n-naughty colt," Fluttershy said softly, practically muttering the tingling words.

Mcintosh responded in kind with a louder moan and an obvious squeezing of his thighs. Even tightly bound behind his chastity cage, Fluttershy could only imagine just how desperate he was getting. To be teased and taunted and played with. She figured if she was in his position she’d be bawling her eyes out, begging for any kind of release. And yet, the stallion maintained his composure, aching and whimpering, but behaving himself like a good colt.

Wanting to feel more, Fluttershy slid a hoof across the length of the diaper, smoothly running it from the base of the stallion's tail to his padded plastic bulge in the front. She could feel the warm, squishy clay inside the diaper mold around her as she nudged the whole mess a tiny bit closer to the front. Mcintosh’s plastic chastity cage felt like an unnatural bump among the sea of swollen, urine soaked padding. It felt naughty knowing that the bulge locked away the stallion’s well endowment and that it grew more desperate with each tease.

“Poor thing,” Fluttershy said, mostly to herself, “l-locked up and unable to...p-play with...me.” She wasn’t going to win any awards for her pillow talk, but still the words made her giddy like a schoolgirl. It was like playing pretend as a little kid, but more exciting and taboo. She found that she really liked teasing!

However she still felt a burning pang of guilt weigh her down as she made such selfish decisions. Her empathy prevented her from ignoring how pent up Mcintosh must have been feeling. Surely it was starting to hurt being teased like this and being physically unable to do anything about it.

But then she glanced down at her shiny key necklace. Mrs. Cake’s and Cream Heart’s advice echoed in her head. She had the key so she called the shots. He had to earn it. He’d just have to stay in his stinky diaper for a little longer until SHE was satisfied.

“O-okay uh...colty,” Fluttershy struggled to say that without a little silly giggle, “lay down on your back.”

Despite how bottled up he was feeling, Mcintosh swallowed a pathetic whine as he did as he was told. Carefully he rolled onto his back, gingerly paying close attention to his squished, messy diaper that hung grossly between his legs. His stinky backside was expertly handled to ensure that it was the last thing to touch the ground, to reduce risk of blow out, Fluttershy guessed. Fluttershy then climbed over him, her own diaper - pristine and white - hovering over the stallion’s face.

With shaky legs, she lowered her crotch, balancing it right on the tip of Mcintosh’s nose. Much like her tentative pat-spanks moments ago, the timid pegasus started things out with an experimental feel, pressing her cushy diaper front into Mcintosh’s muzzle for only a second or two. The pillow-like material crinkled as it creased over the stallion’s muzzle. The prod through the diaper could be easily felt by her sensitive sex, making her nibble on her lip, squeak, and quickly raise herself up off of the stallion’s face shortly after.

Lowering herself again, she dared another press, sending cool shivers down her spine. And then another, followed shortly by another. The prods turned into presses and promptly the presses turned into full on grinding. Soon the primal pursuit for pleasure quickly took over the diapered pegasus and she began to bear down on the stallion’s face, grinding her pampered pussy firmly against him.

Between thrusts, she’d peek through squinting eyes to see Mcintosh’s diaper laying inches under her. Her nose tickled at the smell of the fragrant, yellow diaper, keeping her in the lewdish mindset of a naughty diaper filly.

All Mcintosh could smell was baby powder and the nursery scents infused deep in the padding of Fluttershy’s diaper. The smell, however, was incredibly intoxicating. As Fluttershy humped and grinded against his face, Big Mac could only lay there, breathing in deeply the mare’s scent that fully encompassed his snout. Every now and then he would moan, sending wonderful vibrations up through Fluttershy’s diaper.

Rhythmic crinkling accompanied Fluttershy’s dry humping. Her pussy grew moist with pleasure as every deep, sensual rub drove her crazy with pleasure. The smell of sex mixed in the air with the stink of poopy diapers as diapers squished and pressed about. The sound of moans mixed with the sound of squishing and crinkling.

Finally she reached her tipping point and in the final throes of her orgasm, Fluttershy lowered her head into Mcintosh’s warm diaper, pressing her snout deep into the squishy, pillowy material. Filling her nostrils with the stinky scent amplified her shivering climax. Her legs quivered, her cheeks flushed with red, and her sex slick with her own juices. No matter how much she squirmed, her heated diaper crotch remained firmly planted on top of Big Mac's snout. One final, encouraging moan from the stallion rumbled her diaper as the front became hotter and more humid than ever before.

Her legs finally gave out after the intense thrusting session and she plopped on top of the large stallion. Big Mac’s full diaper served as a convenient pillow for the recovering pegasus and she reveled in the subtle warmth that emanated from the musky padding. Meanwhile Mcintosh blushed underneath Fluttershy’s padding. No matter how he tried to breathe, the overpowering scent of baby powder filled his lungs. It was like the smell was inescapable while he remained pinned underneath the petite padded pegasus.

After her break in blissful afterglow, Fluttershy eventually found the strength to once again pull herself off the broad shouldered stallion. For a moment their eyes met and in her post-orgasm clarity she couldn't help but blush. Big Mac only smiled a polite smile, hardly minding the fact that she used him as her own personal breeding stand. Like the well behaved colt he was, he took it all in stride.

Once again Fluttershy glanced down at her key necklace that now dangled and shined in the dim nursery light. Mcintosh's good behavior wasn't lost on the yellow pegasus. He was so well behaved throughout all that, even when she pleasured herself while neglecting his own comfort. She could have easily unlocked him for being such a good boy. He had certainly earned it after that.

Or...she could tease him for just a little while longer.

With this new mischievous thought in mind, Fluttershy scanned the room around them for inspiration. It was certainly a well equipped and well stocked nursery. Any basic comforts one would expect from a normal nursery could easily find an adult sized version of it here. Besides the cribs and changing table, the nursery also came well stocked with a bookshelf of colorful bedtime story spines, piles of plush animals, and an open chest full of fun looking toys.

“S-stay right there!” Fluttershy chirped as she carefully crawled off of the red stallion.

Digging into the mess of toys, Fluttershy came back with wingfuls of brightly colored hunks of plastic and huggable stuffed animals. There was no method to her selection. Instead she grabbed whatever she could to pile around the stallion. She wanted it to look like the big stallion was in the midst of playtime, too distracted to even pay attention to his diaper which had become deeply stained with browns and yellows. She giggled to herself at the scene she played in her head. It all started to come together as she handed off a large, pink teddy bear to the diapered stallion.

“And and put this plushie between your legs l-like you’re trying to grind against it!” Fluttershy stifled a giggle as she surrounded the stallion with the nursery’s toys. Mcintosh blushed, but climbed on top of the big teddy bear all the same. He now resembled a mischievous little colt, getting into trouble with his mess of toys. The teddy bear, just about as big as Mcintosh himself, seemed to fit nicely between his legs with it's cute buttoned face pressed firmly against his stinky diaper. “N-now don’t you move from that spot,” Fluttershy gulped, “I-I’m gonna uhm...get Mrs. Cake to change your...stinky pants.”

And with that, Fluttershy trotted out of the room, closing the door behind her.

Author's Note

And the diapered adventures go on!

Sometimes I think what really keeps me writing this story is the cover art. Every time I look at it it's just, gosh, it's just an adorable scene! it makes me feel all fuzzy and warm inside and I just hope that I can capture that sensation in what I write!

Chapter Ten

Leaving behind the scene that was equal parts cute and arousing, Fluttershy trotted her way downstairs. She did well to suppress any giddy squeaks that wanted to sneak past her little smile as she further distanced herself from the nursery. The smell of lavender and the subtle stench of stale urine was slowly replaced by lemon scented cleaner and the smell of preheating ovens.

Mrs. Cake was found in the kitchen, still cleaning things up from yesterday's party. It was as if the building was going through a transformation. No longer a hothouse of diaper wearing ponies who spent their day covering their faces with mushy food and shamelessly rubbing their padded crotches. The place was now starting to once again resemble a place of business. Glass paned display cabinets emerged from under tarps, card tables were folded up and put back into storage, and fun looking toys were boxed up and hidden away until next time. Slowly the remnants of yesterday’s party were being packed away.

Carrot Cake scurried around in the background, still wearing his soaked morning diaper. With plans of opening the store tomorrow, there was still plenty to do for both ponies. Sweets needed to be made, pastries baked, and cakes decorated. While Mrs. Cake tended to the remaining guests of the party, he oversaw the number of cookies and treats that cooled on the countertops, all the while his cool, soggy diaper sloshed and rustled behind him.

“Uhm...M-Mrs. Cake?” Fluttershy started with a small voice.

“Yes, Shyshy, what is it?”

“Me and Big Mac are...done playing and uhm...” Fluttershy’s eyes dropped to her feet, “he still needs to be changed.”

“Kept him stinky and locked up this whole time?” Mrs. Cake inquired, “my, Fluttershy, I didn’t think you were such a naughty little filly!” She rustled Fluttershy's hair, causing the pegasus to blush up a storm. “Well I guess I better go change him then. Wouldn’t want him waddling around the place and getting a rash!”

With that, Mrs. Cake trotted upstairs and Fluttershy felt obligated to follow. Afterall, in a way she was partly responsible for how dirty Mcintosh had become. It just didn't feel right to leave all the cleaning up to Mrs. Cake. At the very least she felt the need to assist in changing such a mess. Or perhaps it was because she'd be able to see his adorably stinky self one last time.

Pausing at the nursery door, the two mares looked into the room and at the adorably silly sight. Big Macintosh, with his swollen and heavily stained diaper, kept true to his word and was right where Fluttershy had left him. He laid among the scattering of colorful toys., cuddled up against the bulk of the big teddy bear with the plushie's snout firmly buried underneath the stallion’s rump, enveloped by the soggy, stinky padding. Fluttershy couldn't lie to herself, she just couldn't get enough of the embarrassingly erotic and cute spectacle! It made her heartbeat pick up again, returning to that excited rhythm that she reveled in just minutes before.

“I take it this was your idea?” Mrs. Cake quietly asked. Fluttershy could only shyly blush as she stifled a little giggle. With a playful roll of her eyes, Mrs. Cake turned her attention to the stinky colt. "Alright, Little Macky, I think you've had enough time to play with your toys."

She trotted into the room and proceeded to give Mcintosh a very thorough diaper check. A hard pat on the butt, an exploitative squeeze at the front, she even pulled the back of Big Mac's diaper to give it an old fashioned sniff check. All the stallion could do was squirm futility with cheeks flaring a bright red. It all felt like Mrs. Cake was putting on a show for Fluttershy.

"Yep, looks like you're in DIRE need of a diaper change!" Mrs. Cake finally concluded, pushing some toys aside to clear an area in the center of the nursery. "Too poopy to try to walk you over to the changing table! We're just gonna have to change you here."

Whimpering some kind of argument, Mcintosh frowned as he pulled away from the mess of toys and rolled onto his back in the all too familiar diaper changing position. The brown stained lump around his butt squelched an embarrassingly loud squish that bad bother diapered ponies blush by association. The mound of swollen, yellow padding bunched up most around his crotch gave the area a deceptively well-endowed appearance.

"P’ew! Just what were you doing in that diaper of yours? You're a mess!" Mrs. Cake continued as she snatched a hoofful of supplies from the changing table, "you know, Fluttershy wasn't nearly as poopy as this!"

It was tough to say who among Fluttershy and Mcintosh blushed and squirmed the most at this comment. Fluttershy shrunk back against the wall when she heard this, muffling a silly feeling giggle with a hoof. Mcintosh would have shied away as well, but the weight of his diaper kept him on his back, forced to have a blushing contest with the ceiling.

Minutes later - an obviously long and deliberately drawn out waiting period - Mrs. Cake had assembled all the necessary supplies and had positioned herself near Mcintosh's bulging waist. She took an even longer time carefully arranging the wipes, the extra diaper, and the baby powder within reach, checking and double checking the items to insure she had enough to proceed. It was only after another five or so minutes did she begin by popping open the tubs of wipes.

Before she got started, however, there was a tentative knock on the open nursery door.

"U-uhm, howdy do, Mrs. Cake, Fluttershy," came Applejack, who stood smally in the doorframe.

Fluttershy stammered out something that resembled a quick "good morning, Applejack!" but it almost came out like a jittery mess when she said it. In an instant she felt startled, nervous, happy, excited, and embarrassed at the sight of her friend Applejack. She noted that she wasn't wearing a diaper and for some reason that shook her mental foundations a bit. In a weird way, Applejack walking around here diaperless made all this feel kind of silly. It all made her want to slink deeper into the wall and disappear.

"Mr. Cake said ya'll'd be up here." Applejack blushed as she continued, "ah didn't think ah'd be interruptin'..." She tried her best not to stare too hard at the scene before her. It was tough to say, at least for Fluttershy, whether she was embarrassed to walk in on her brother getting a diaper change or incredibly excited by it.

"Oh Applejack! You're not interrupting anything! Just changing your baby brother's diaper!" Mrs. Cake explained so casually, even going as far as to lift Mcintosh's muscular hind legs up into the air to show off the backside of his diaper which had become smoothly flattened by the pancaked mess inside. "Will you be staying long? Can I get you something?"

“A-ah only swung by to grab Big M-Mac," Applejack answered as she sporadically stared at Mcintosh's situation. She gulped down some nerves. "A-ah didn't know he'd still be...busy."

"Oh no, not busy at all!" Mrs. Cake chirped, "once we get this poopy thing off, he'll be all ready to go to his big boy chores."

"'Course, then he'd have ta have his cage unlocked..." Applejack muttered.

All eyes in the room turned to Fluttershy, the keeper of Mcintosh's key. The meek pegasus, never really being a fan of the limelight, shrunk back. She felt the cold metal of her key chill her chest.

"W-well I-I guess if he has chores to do..." she stammered, rolling the key around with a hoof.

"There's a good girl," Mrs. Cake praised before glancing over at Applejack.

The orange pony was caught staring at Fluttershy’s key for a little too long. Applejack always seemed so twitchy when it came to all this diaper stuff. One-on-one she'd admit to being into a lot of the stuff, but she often played with others with a hint of reservation. She always kept herself in check, never fully relaxing. And the motherly mare could read her like a book.

Interpreting all the signals she needed to, Mrs. Cake stood up from her spot beside Mcintosh and handed over the open tub of wipes. “And YOU get to finish cleaning him up.”

"What?!" Applejack exclaimed.

"If you want his help then he's your responsibility, honey."

There was a beat. Any hint of that vicarious embarrassment-excitement that once hung on Applejack’s face was now replaced with a pale faced sickness. She enjoyed wearing diapers, that was obvious, but messy diapers, whether it was wearing or changing was something she was firmly not into. It was the texture and the smell, that repulsive smell. Even wet diapers were sort of pushing the earth pony’s limits. At least wet diapers had that glowing warmth that hung under you like a weighted blanket. At least wet diapers didn’t cling to your fur and smear everywhere.

Her eyes darted between the tub of wipes and Mcintosh for a moment. There was a clear indication in her eyes that she wanted to outright refuse. Changing her older brother’s stinky diaper. It was a chore she would have very much preferred not doing. But Mrs. Cake had a knack for convincing others to do what she wanted.

In the end, Applejack just silently nodded and grabbed the container of wipes out of Mrs. Cake’s hooves.

Opening the diaper unveiled a terrible, sour stench and the squishy insides of the messy diaper Mcintosh had been stewing in this whole time. What didn’t cling to his muscular backside was smushed all around the back of the diaper, leaving very little of it clean. Above the awful, brown pile of muck sat the stallion’s caged junk, which despite the embarrassing fact that he was getting his diaper changed by his little sister - and the fact that the cage was still firmly locked around it - throbbed ever so subtly behind its blue plastic binding.

Applejack recoiled at the mess, already growing a little green around the gills. “Ugh, did you really have to get it so...full?”

Mcintosh didn’t say anything, but Fluttershy noticed an ever so subtle smile grow on his face as he silently leaned back and spread his legs further apart. It looked like a sort of vengeful role reversal for all those poopy diapers he had to change when the pair were kids.

Doing her best not to breathe or look directly at the mess plastered all over her older brother’s backside, Applejack pulled up her first moist wipe and went to work. Wipe after wipe, she cleaned - or more accurately scraped - the mess off of the stallion’s rump. Under Mrs. Cake’s watchful eye, she made sure to give the area a thorough cleaning. She used a dozen wipes to clean up the mucky mess that covered Big Mcintosh’s rump from end to end. Progress was slow and there were a couple times when she had to lean away from the scene to catch a breath of the freshest air she could manage, but progress was progress.

Once the diaper was safely disposed of into the pail, Applejack allowed herself to take a deep, open mouthed breath. The pungent stench still hung in the air long after the diaper was gone, but sometimes she managed to catch a whiff of the fresh lemon scent of cleaning products. She found a little bit of solace knowing that the smell of poopy diapers wasn’t forever burned in her nostrils.

"There, that wasn't so bad, was it?" Mrs. Cake cooed once the other mare recovered, "Fluttershy dear, would you care to unlock our little diaper boy's cage now?"

Again, everypony looked at Fluttershy, hanging in anticipation of her next decision. No one hung on the suspension more than Big Mcintosh, who silently begged with his eyes. After a long, drawn out pause, Fluttershy finally nodded shyly, emerging from her spot against the wall with the key shining in the afternoon light.

All eyes followed her as she glided up to Mcintosh who whimpered quietly in frantic hope. His legs splayed out wider now, his freshly cleaned chastity device gleaming in the sunlight. He was SO ready for this and only prayed that he had earned the right to be freed of his chastity.

The key slipped into the device’s lock, clicking loudly in the still room as it opened with a single twist. The hunk of plastic fell to pieces without the lock, disassembling itself around the stallion’s ready cock. Mcintosh let out a sheepish sigh as he went back to staring up at the ceiling. Gone were the painful bindings that constricted and kept his boyish instincts at bay. Now he no longer had to wince every time arousal became too strong.

Free from the cage, Big Mcintosh’s cock immediately grew in length, springing up at attention between his legs. Fluttershy’s eyes grew wide at the spectacle. Turns out the stallion was much more...endowed than she gave him credit for. One massive trunk of a dick stood high between his legs, accompanied by two large orbs that swelled from a weekend’s worth of teasing and edging. He moaned with relief once the whole thing unfolded. It was an immense relief, almost a pleasure all it’s own.

“Might be a good idea to take care of...that before you waddle on home, sweetie,” Mrs. Cake said, eyeing the throbbing length that twitched at the ready. “I’m sure I can dig up something our little diaper butt can play with so that he’s not walking home with a stiffy,” she went on before looking up at Applejack and Fluttershy, “unless anypony else wants to help him out...?”

“C-Could -I- do it?” Fluttershy suddenly found herself saying. The words seemed to slip out of her mouth at that very moment. She bashfully looked around the room, noticing Applejack opening her mouth to say something, before closing it back up before taking a shy step back..

“Well you are his keyholder,” Mrs. Cake reasoned, “it’s up to you, sweet roll.”

She glanced over to Mcintosh and then back at Mrs. Cake. “I-I would l-like to...v-very much...”

“Well how can I refuse such a polite little pony,” Mrs. Cake smiled, nudging Applejack - who at this point appeared to have petrified herself by blushing too much - out of the area around Mcintosh, “then he’s all yours, honey.”

Fluttershy’s eyes switched between Mcintosh’s eyes and his...natural endowment as she kneeled beside the stallion. Their eyes met and a new kind of energy buzzed between the two. He watched her with intense and eager eyes, practically beckoning her over with his stares alone. His shivering only intensified as Fluttershy’s head slowly lowered closer to his throbbing cock. She leaned in so close that he could feel her breath on him. His hooves dug into the carpet as he held onto what minute amount of self control he still had left.

Fluttershy tested things by tentatively running her tongue up the length of Mcintosh’s member. It tasted sweaty and musty with a faint urine saltiness to it. From the base near the balls to the very tip that glistened with pre-cum, her tongue slicked across the veiny, heated surface, punctuated at the end with a little, dainty kiss on the tip. Her tongue danced around the head, moistening the whole thing up and sopping up the salty sweet beads that gathered around his throbbing tip.

Mcintosh could only moan and quiver under Fluttershy’s touch. He was like puddy in her hooves. After spending so long being so bottled up, he shamelessly moaned and grunted, whimpering like a puppy. Every tiny little sensation felt like firecrackers to the unrestrained stallion. It was enough pleasure to make any pony get carried away.

And carried away he did.

Not ten minutes after Fluttershy had started, Mcintosh pulled in a sharp breath. Seconds later his cock tensed up before spraying its load high into the air. The sticky strings arched in the air before raining back down on the unsuspecting ponies, tagging Mcintosh’s fuzzy belly as well as Fluttershy’s long pink mane.

Fluttershy could only blink at the sight as she leaned back. A splotch of semen matted a section of her mane and pulled it closer to her forehead. “Oh...” She could only say, surprised, puzzled, and a little disappointed. Was that it? Was that what all this was building up to? Was she teasing him too much? Should they have really moved on to...bigger things? Did semen stain carpet?

She didn’t have too long to worry about this because soon after Mcintosh’s climax, the stallion returned to the world of the living. He panted and quivered as he rolled off his back and wordlessly motioned Fluttershy to follow through. The two of them stood up and he then slipped behind Fluttershy. By then his cock, powered by a healthy stallion stamina, was stiffening up again, ready for round two.

Mrs. Cake and Applejack meanwhile stood quietly at the door, waiting patiently for the two mischievous foals to finish up. Mrs. Cake looked at the adorable sight like any caring mother would. Meanwhile Applejack never seemed to stop blushing and, despite her nervous and secondhand embarrassment, watched the whole thing. Although, she seemed to be enjoying it as far as Fluttershy could tell, because she was quick to notice the insides of Applejack’s thighs were growing slick with moisture.

Big Mcintosh’s advances started with pushing Fluttershy’s diaper aside. The chilly outside air tickled the mare’s butt as the diaper moved away to reveal her moist, pink pussy. Thoroughly lubed up by Fluttershy’s spit, Mcintosh slipped into her with no problem at all.

Fluttershy gasped as the large, girthy mass pushed into her. Her back legs twitched as butterflies began to dance in her stomach. The massive cock filled her up to the brim as she shivered with pleasure. Big Mac slowly pushed into her, slipping inch by inch until he could go no further before pulling back out. That thrust was followed by another and then, after a hesitant pause, another.

Fluttershy moaned amidst her gasping, or at least tried to, however any moaning that came naturally out of her lustful advances came out as more of a squeak. But at least they were pleasure filled squeaks. To be overtaken by such a big, burly stallion was intoxicating. She had never felt anything like it. The fullness of his cock. The painful pleasure each time it slid in and out of her. Even the diaper nestled against her crotch, an otherwise forgotten accessory, encouraged her along by pressing against her with every hump.

Meanwhile Big Mcintosh was in seventh heaven, grunting between clenched teeth after every thrust. For so long his stallionhood was kept locked away, but now he was free to dive into whatever sexually craved impulse his body screamed for. There was a vigor in his motions. An electric energy that drove his advances with passion and power.

The pair remained close to each other’s embrace for what felt like an eternity. Every thrust was filled with pleasure and every breath they took tingled with a dozen bolts of electricity. They slipped into a pulsing pattern, thrusting, panting, and the intermittent moan. Big Mac’s cock shlucked slickly in and out of Fluttershy’s slit, ridgid and sure. Meanwhile Fluttershy fought against gravity as her forelegs quivered under her weight from the potent pleasure that empowered every inch of her sensitive body.

Finally before long, Mcintosh’s body shook and his breath shivered as a hefty load of white cum came shooting out of his cock. Fluttershy gasped as she felt her pussy fill up with the sticky mess, serving as just the trigger her body needed. Her muscles tightened up in response, her breathing cut short, and finally her body erupted with euphoric pleasure, further adding to the sexual juices that coated the inside of her soggy diaper. She emitted something of a gasping moan, rather louder than she was used to, and dropped to the ground in weak exhaustion.

Meanwhile Mcintosh huffed, quivered, and twitched as he was left almost comatose from the earth shattering orgasm. His spent penis throbbed in the final throes of his afterglow, softening quickly once its load had been thoroughly exhausted. His heavy breaths heaved as he slowly pulled his stallionhood out of her warm pussy before collapsing to the ground. Now, after his second try at it, he was finally satisfied.

Fluttershy’s legs felt like gelatin as happy sighs flowed out of her open mouth like a gentle stream. Her body continued to buzz as her mind remained foggy in her bliss filled afterglow. She was only distantly aware of the world around her now. The voices around her were muffled, obscured by the glittering warmth of her recovering body.

"Theeere's a good boy," Mrs. Cake chuckled amidst the fuzzy afterglow. "Gosh, he really needed to go, huh? You can take him home now, Applejack."

"O-oh! Y-yeah...I-I'll just go ahead and...take him home...for those chores..."

Fluttershy remained where she laid, with her face pressed into the soft carpet and her rustled up diapered butt hanging in the air. Even if she wanted to, she couldn’t budge an inch. She reveled in euphoria. An unmatched satisfaction she had never had the pleasure of experiencing before.

"A-alright Big Mac, let's...get ya home," Applejack said, helping the larger stallion up onto all four feet.

In his momentary daze of pleasure, Big Mcintosh was practically asleep on his feet. He could just about stand up straight, but his balance was right on the edge of fault. There were times Applejack had to lean her entire weight up against the lethargic stallion, directly his slumping body out of the room. All the while he wore this fog brained smile on his face.

“Be s-seeing ya, Mrs. Cake, Fluttershy,” Applejack managed to stutter out as the two left.

With the Apples gone and well on their way back to the farm, Mrs. Cake tended to Fluttershy who continued to lay frozen with her butt hanging high in the air. She took this moment to smooth out the filly’s wrinkly diaper and repositioned it back over her bottom.

“Bathtime for little fillies,” Mrs. Cake cooed shortly after before helping Fluttershy up to her feet.

Author's Note

Well, I rather like how this chapter turned out. It's certainly been building up to this point, hasn't it? I'm surprised this little idea got us TEN CHAPTERS worth of content! I hope everyone's been enjoying it so far!

I feel this story has maybe one or two more chapters left after this, just to wrap everything up that's already been put on stage into a neat little bow. It's a good stopping point and I feel the story has reached a logical conclusion. Fluttershy has learned more about a new side of herself and figuring out how this affects her life outside of the party has some potential for sequels down the road. I don't know what those sequels would involve or when I'll actually get to writing them, but it's something to think about in the future!

Chapter Eleven

The short trip to the bathroom allowed Fluttershy’s mind to slowly return to her. For the past ten or fifteen minutes, it was vacationing in the misty clouds above. An expression of what could be best described as “blissful satis-floatiness” seemed perpetually glued on her face. Her wings felt like they were made of tingly lightning and her whole body glowed even when her backside was left raw and achy from Mcintosh’s...rather healthy advances.

She wobbled as she walked. A sort of mix between a toddler waddle and a sailing pony who had not yet gotten their sealegs. With her mind half-vacationing, she didn’t feel entirely in control of her body.

Her diaper was wrinkled and quite sticky inside. Maybe even a little wet in some patches from the occasional moments where her excitement got away from her. It’s absorbent inner layers gladly soaked up the dribbles of stallion cum that leaked out of her.

Everything felt so distant to her in this mindset. Miles away she could faintly hear the bath being drawn. Five hundred yards away she could feel the tile floor chilling her hooves. And no less than fifty feet away, she could feel her diaper being removed. It wasn’t until her body was half submerged in warm, lavender scented water that she managed to gather herself.

Mrs. Cake had drawn her a relaxing bath to help the stunned pegasus simmer back to reality. No playful bubbles were added, but soothing aromatics wafted off the warm waters. The aches and pains that coiled themselves deep in her back and stiff wings melted under the water like hot wax. She found it much easier to rest her rump, which was left painfully tender, once it was all under the water.

"Guess it might be time for you to head on home too, huh?" The motherly mare commented, raising one of Fluttershy’s hooves to give it a good scrubbing.

"Oh...yeah I suppose so," Fluttershy replied. She had too much sense to say otherwise.

Although there was a little part of her that ached to admit it, she had things to do back at home. There were bird feeders that needed to be refilled, pens to be cleaned, plus Angel Bunny was always so ornery when she was gone for too long. The party was a fun little break from all that, but the responsible side of her mind notified her that there were animals back home that depended on her. Already the more studious part of her mind was returning from its vacation and making a mental list of her chores.

She was so caught up in assembling her work schedule that the whole bath passed like a blur. As she contemplated feeding schedules for the returning flocks of migratory birds, Mrs. Cake had already scrubbed her fur clean, doused her pink mane with shampoo and water and already had the pegasus out of the water and dried off.

"I had a lot of fun over here," Fluttershy finally said.

"I'm happy to hear it!" Mrs. Cake replied, now brushing the other pony’s mane.

"Thank you for inviting me to your little party," Fluttershy then added, “I really appreciate you thinking of me.”

"You're quite welcome, Shyshy," Mrs. Cake beamed, "I'll be sure to add you to the guest list when we have another one!"

"Oh gosh...I'd really like that..."

And she was really REALLY looking forward to that. Presently she needed time to digest what she had experienced over the past couple of days. There was a lot of it she knew she hadn’t properly processed yet. But gosh, she was eager to experience more!

By the time she was dried off and ready to head home, her feathered wings bristled with excitement and anticipation. She stood at the front door of Sugarcube Corner with an eager buzzed expression on her face.

Mrs. Cake returned moments later with a pair of saddle bags made of a tan canvas. "A little care package to take home with you," she explained, rolling open the top flap, "we got you some spare diapers, onesie, pacifier, and a couple toys for you to play with."

"Wow, this is all so...so generous! Thank you!"

Mrs. Cake proceeded to drape the saddle bags over Fluttershy’s back. "I know I'm always a short walk away, but keep these things handy in case you get a little needy one night, okay?"

Fluttershy nodded. The achiness of leaving all this came back, only this time it felt more real. Sure she could always come back, it was a short walk after all, but she then began thinking of how she might feel at night. How she won’t have a caring mare to cuddle with or cry to when she was all alone at night. The bristled excitement began to falter and before she knew it she started to dwell on being alone. So very very alone.

Her thoughts were cut short when she was pulled into Mrs. Cake’s chest for a big hug. In an instant, those worrisome thoughts evaporated.

"And don't think I forgot about our tea time on Wednesday," Mrs. Cake added once their prolonged hug finally ended, "I got Carrot whipping up some of those orange tea biscuits you like."

Fluttershy brightened up at this. “O-oh yeah, I almost forgot!” Tea time, of course! She’d see Mrs. Cake again then!

"Have a safe walk home, Shyshy," Mrs. Cake winked, "we'll be seeing each other soon."

“Bye for now, Mrs. Cake,” Fluttershy smiled and the two parted ways.

And with that, Fluttershy headed back home, trotting down the familiar cobblestoned road that connected Ponyville proper to the outlying buildings on the edge of town. The route was a well traveled commute for the yellow pegasus. However today everything felt...strangely brighter. It was like the path itself got a whole new lease on life recently and was making sure anyone who traveled on it had a nice day as well. Things looked brighter, things sounded brighter, and things even felt brighter.

Fluttershy noticed she had a chipper bounce in her step. A happy song in her heart as her hooves clopped against the stony ground. To think this was only the beginning! And maybe when she got home, if she was extra good and did all her chores like a good girl, she’d even reward herself with a little diaper time.

Author's Note

And there we have it, everyone. The final chapter for Cake Party. Although there's always a demand for some juicy diaper pony action, I feel this story in particular has reached it's logical end. I do hope everyone enjoyed the story! I certainly enjoyed writing it! At least now my muse can shut up about how cute it'd be if Fluttershy and Big Mcintosh wore diapers together.

Anyway, thanks for reading! Hope everyone has a lovely week!
